Introduction
Introduction
The Command Reference, a comprehensive guide to AutoCAD for Mac®
commands, lists all AutoCAD for Mac commands in alphabetical order.
In addition to the command listings, the Command Reference covers several
topics in the appendixes: command aliases, system variables, dimension
variables, utilities, standard libraries, graphical database objects, and Unicode
fonts.
Using AutoCAD for Mac Documentation
In addition to this Command Reference, several other resources are available to
help you learn and use AutoCAD for Mac. The complete documentation set for
AutoCAD for Mac is online. You can access it from the Help menu.
NOTE For the latest documentation corrections and additions, refer to the Readme
file.
Using This Reference
The Command Reference provides detailed information on all commands,
command options, and system variables. The explanations reflect the default
AutoCAD for Mac system variable settings and the default prototype drawing.
If you change system variable settings, the prompts on your screen might differ
from what you see here. For example, the setting of the FILEDIA (page 1296)
1
1
system variable governs whether you work in a dialog box or at the command
prompt when you use certain commands. See appendix B, System Variables.
Executing Commands
The process of executing a command begins by starting the command, using
one of several methods. For some commands, such as REGEN (page 877) , no
further action is required. For other commands, you must respond by providing
additional information or actions in order to complete the command.
As you work with commands, note that right-clicking in the drawing area
either acts as Enter or displays a shortcut menu. You can control this behavior
in the Application Preferences dialog box or with the SHORTCUTMENU (page
1429) system variable.
Starting Commands
You can start a command by doing one of the following:
Select the command from a menu, tool set, status bar, or shortcut menu.
Enter the command name or command alias at the Command prompt
and press ENTER or SPACEBAR.
In this Command Reference, near the beginning of each command description
is a command access section, listing the specific ways you can start that
command. For example, following is the command access section for the PAN
(page 763) command:
Menu: View Pan Realtime
Toolbar: Status bar
Shortcut menu: With no objects selected, right-click in the drawing area,
and choose Pan.
Command entry: pan (or 'pan for transparent use)
The availability of certain shortcut menus depends on the current setting of
the SHORTCUTMENU (page 1429) system variable. The instructions in the
command access sections assume that you have made the indicated menu
available.
You can exit a command at any time by pressing ESC.
2 | Chapter 1 Introduction
Using Transparent Commands
In many cases, you can start a command while using another command. The
command you start is called a transparent command. For example, to turn
on the grid while drawing a line, you can start the GRID (page 467) command
transparently by preceding the command with an apostrophe. Two right angle
brackets (>>) precede prompts for transparent commands.
Command: line
Specify first point: 'grid
>>Specify grid spacing(X) or
[ON/OFF/Snap/Major/aDaptive/Limits/Follow/Aspect] <current>:
on
Resuming LINE command
Specify first point:
In the Command Reference, the command access sections identify commands
that you can use transparently.
Suppressing Dialog Boxes
Many commands provide both command prompt and dialog box interfaces.
In most cases, when both a command prompt and dialog box interface are
available, the command prompt version is preceded with a hyphen character.
For example, the command prompt version of ATTDEF (page 106) is -ATTDEF.
You can also control the display of file dialog boxes through the FILEDIA
(page 1296) system variable. See appendix B, System Variables.
Responding to Prompts
If a command does not immediately execute, AutoCAD for Mac either displays
a dialog box or displays command prompts requesting more information.
Command prompts are structured as follows:
Command: commandname
Current settings: Setting1 Setting2 Setting3
Instructional text [Option1/oPtion2/opTion3/...] <default
option or value>:
The optional current value line displays the current settings for the command
or for system variables related to the command. The succeeding prompts
identify the type of input required to complete the command and, when
applicable, list the available options in straight brackets and a default option
or value in angle brackets. In some cases, AutoCAD for Mac determines default
Introduction | 3
options and values based on the option or value that you last specified, or
based on the settings of certain system variables.
Typically, the first word of a prompt indicates the type of action you can take.
Most command prompts begin with the wordenter, select, or specify. These
words indicate how you can respond to the prompt.
Terminology in command prompts
You can...If the prompt starts with...
Select objects on the screen using your pointing
device.
Select
Enter text at the command prompt.Enter
Use your pointing device or enter text at the
command prompt to select a point location on
the screen.
Specify
Selecting Options at the Command Prompt
To select one of the options contained within the straight brackets, you can
enter the entire option name or only the capitalized letters, and then press
Enter or Spacebar. To select the default option enclosed in angle brackets (<>),
if available, press Enter or Spacebar.
You can also choose command options from a shortcut menu by right-clicking
in the drawing area while the command is active. The options available at the
command prompt appear in the shortcut menu. For information about how
to enable or disable this shortcut menu, see Shortcut Menus in the User's
Guide .
Entering Data at the Command Prompt
Some prompts ask you to enter data, rather than (or as an alternative to)
choosing an option. To do so, enter the text at the command prompt and
press Enter or Spacebar. However, be aware that when the command prompt
requests an object name, Spacebar inserts a space at the command prompt
rather than acting as Enter. This allows for the support of extended symbol
names.
Just as default command options are often provided, prompts may include
default values, enclosed in angle brackets (<>), when data is requested. For
4 | Chapter 1 Introduction
example, the POLYGON (page 821) command displays the following prompt,
suggesting 4 as the number of sides for your polygon:
Command: polygon
Enter number of sides <4>:
To accept the default value, press Enter or Spacebar.
Using Wild-Card Characters at the Command Prompt
When the prompt directions ask for a name list, such as a block name, variable
name, named view, and so on, you can use wild-card characters to specify
names. See the table in Filter and Sort the List of Layers in the User's Guide.
Repeating Commands
If no command is active, you can repeat the previous command by pressing
Enter or Spacebar or by right-clicking in the drawing area and choosing the
Repeat Command Name option from the shortcut menu.
Accessing Recently Used Commands
You can access the six most recently used commands from a shortcut menu
by right-clicking in the command window and choosing Recent Commands.
References to Other Sections
At the end of most command descriptions, you'll find a section called See
Also. This section includes references to chapters in other AutoCAD for Mac
guides and other AutoCAD for Mac commands and system variables related
to the current command.

the corner point of the box.
Height of Box Specifies the height of the box. Enter a distance or specify a
point relative to the corner point of the box.
Rotation Angle Rotates the box about the first corner specified. If you enter
0, the box remains orthogonal to the current X and Y axes.
Copy Creates a rotated copy of the box.
8 | Chapter 2 Commands
Reference Aligns the box with other objects in the drawing or relative to an
angle you specify. The base point for the rotation is the first corner of the box.
Reference Angle:Defines a reference angle by specifying two points or
an angle from the X axis on the XY plane. For example, you can rotate the
box to align two specified points on the box with a point on another object.
After defining a reference angle, specify a point for the reference angle to
align with. The box then rotates around the first corner relative to the
angle of rotation specified for the reference angle.
If you enter 0 as a reference angle, the new angle determines the rotation
of the box.
New Angle:
Specify a point relative to the base point. The base point for the rotation
is the first corner of the box. The box rotates by the angle between the
reference angle and the new angle. If you want to align the box with
another object, specify two points on the target object to define the new
angle of rotation for the box.
If the reference angle of rotation is 0, the box rotates the angular distance
entered relative to the first corner of the box.
Cube
Creates a cube using the length for the width and height of the box.
Center Point for Base
Radius for Base
Radius for Top
Specify rotation angle of box about the Z axis or [Reference]: Specify an angle
or enter r
Rotation Angle Rotates the cube about the first corner of the box. If you enter
0, the box remains orthogonal to the current X and Y axes.
Copy Creates a rotated copy of the cube.
Reference Aligns the box with other objects in the drawing or relative to an
angle you specify. The base point for the rotation is the first corner of the box.
Commands | 9
Specify the reference angle <0>: Specify a point, enter an angle, or press Enter
You can define a reference angle by specifying two points or an angle from
the X axis on the XY plane. For example, you can rotate the box to align two
specified points on the box with a point on another object. After defining a
reference angle, specify a point for the reference angle to align with. The box
then rotates around the first corner relative to the angle of rotation specified
for the reference angle.
If you enter 0 as a reference angle, the new angle alone determines the rotation
of the box.
Specify the new angle: Specify a point or enter an angle
To specify the new angle of rotation, specify a point relative to the base point.
The base point for the rotation is the first corner of the box. The box rotates
the angular distance between the reference angle and the new angle. If you
want to align the box with another object, specify two points on the target
object to define the new angle of rotation for the box.
If the reference angle of rotation is 0, the box rotates the angular distance
entered relative to the first corner point of the box.

The base point of the source object will be moved to the base point of the
destination.
Specify second point or [Continue] <C>: Specify a point on the objects
X axis, or press Enter to skip forward to specifying destination points
The second point specifies a new X axis direction within a plane parallel to
the XY plane of the current UCS. If you press Enter instead of specifying a
second point, the X and Y axes are assumed to be parallel with the X and Y
axes of the current UCS.
Specify third point or [Continue] <C>: Specify a point on the objects

3DARRAY
Maintains legacy behavior for creating nonassociative, 3D rectangular or polar
arrays.
Access Methods
Button
Menu: Modify 3D Operations 3D Array
Toolbar: Modeling tool set Copy tool group 3D Array
Summary
3DARRAY functionality has been replaced with the enhanced ARRAY (page
86) command, which allows you to create associative or nonassociative, 2D
or 3D, rectangular, path, or polar arrays. 3DARRAY maintains legacy behavior.
20 | Chapter 2 Commands
For 3D rectangular arrays, in addition to columns and rows, you also specify
the number of levels in the Z direction. For 3D polar arrays, you specify the
axis of rotation with any two points in space.
The entire selection set is treated as a single element in the array.
List of Prompts
The following prompts are displayed.
Enter type of array [Rectangular (page ?)/Polar (page ?)]
<R>: Enter an option or press Enter
Rectangular Array
Copies objects in a matrix of rows (X axis), columns (Y axis), and levels (Z
axis). An array must have at least two rows or two columns or two levels.
Specifying one row requires that more than one column be specified, and vice
versa. Specifying one level creates a two-dimensional array.
Positive values generate the array along the positive X, Y, and Z axes. Negative
values generate the array along the negative X, Y, and Z axes.
Commands | 21
Polar Array
Copies objects about an axis of rotation.
The specified angle determines how far the objects are arrayed about the axis
of rotation. A positive number produces a counterclockwise array rotation. A
negative number produces a clockwise array rotation.
Entering y or pressing Enter rotates each array element.

3DCONFIG (-3DCONFIG)
Sets options that affect 3D display performance.
Summary
Enter -3dconfig at the Command prompt to use this command.
List of Prompts
The following prompts are displayed.
Enter option [Dynamic tessellation (page ?)/General options
(page ?)/acceLeration (page ?)/Plot emulation (page
?)/eXit] <Adaptive degradation>:
Dynamic Tessellation
Sets the options that determine the smoothness of the objects in a drawing.
Objects are drawn using many short lines (or triangles when drawing spheres).
These lines are called tessellation lines. Objects in your drawing appear smoother
when you use more tessellation lines.
22 | Chapter 2 Commands
Surface Tessellation Determines the amount of detail for surfaces in your
drawing. A higher setting provides more detail but uses more tessellation lines
and more memory.
Curve Tessellation Determines the amount of detail for curves in your
drawing. A higher setting provides more detail but uses more tessellation lines
and more memory.
Number of Tessellations to Cache Configures your system according to
memory and performance requirements. The 3D cache always stores at least
one tessellation. When this option is set to 1, the tessellation for all viewports
is the same; some objects in the drawing may be regenerated as you zoom in
and out. Setting this option to 2 or more is useful when you have more than
one viewport with different views. Increasing the number requires more
memory.
General Options
Sets performance-related options that are not hardware dependent.
Discard Back Faces Discards back faces when drawing objects. You cannot
see the effect of discarding back faces on some objects, such as spheres, because
you cannot see the back face even when it is present. The effect of discarding
back faces is visible on objects such as those that don't have a top. Discarding
back faces enhances performance.
Transparency Quality Adjusts the transparency quality. At the Low setting,
a screen-door effect achieves transparency without sacrificing speed. At the
Medium setting, the default in software mode, blending improves image
quality. The High setting, the default in hardware mode, produces an image
free of visual artifacts at the cost of drawing speed. Materials must also be
turned on for transparency to be visible.
The General Options prompt is redisplayed.
Acceleration
Specifies whether to use software or hardware acceleration in 3D.
If you select Hardware, you can also specify whether geometry acceleration
are turned on or off.
Hardware Specifies hardware acceleration. The hardware graphics card
performs most of the drawing tasks in 3D to increase performance.
Driver Name. You can select a driver from a list of available
hardware-accelerated drivers found in the Drv directory. If you want to use
a hardware driver from another vendor, it must be supported by the Heidi®
Graphics System.
Commands | 23
Enhanced 3D Performance. Enables a more efficient use of the
graphic card when working with 3D objects.
NOTE
If you experience problems with precision, turn this option off.
Smooth display. Controls the status of the full screen anti-aliasing
effect. This option removes the jagged effect on the display of diagonal
line and curved edges.
Advanced material effects. Controls the status of the advanced
materials effect on screen.
Gooch hardware shader. Enables the use of Gooch shading. With
this option on the details of a 3D object are shown by softening the
contrast between lighted areas and shadowed areas by using warm and
cool colors as a substitute to light and dark colors.
Per-pixel lighting. Enables the computation of colors for individual
pixels. With this option on the 3D objects and lighting effects appear
smoother in the viewport.
Full shadow display. Enables shadows to be displayed in the
viewport.
NOTE
Enhanced 3D performance effect must be turned on.
Texture compression. Enables the use of texture compression to
reduce the amount of video memory required to open and display a
drawing that contains materials with images or has attached images.
NOTE
With this option turned on, the time it takes to load the images might
increase the first time that they are accessed, and there is a reduction
in the quality of the images when they are displayed in the viewport
or plotted.
Software Feature is not supported and is provided for scripting compatibility
only.

After entering the last two points for a 3D face, the command repeats
automatically using the these two points as the first two points of the next
3D face. For example:
List of Prompts
The following prompts are displayed.
Specify first point (page 31) or [Invisible (page 31)]: Specify
a point (1) or enter i
First Point Defines the start point for the 3D surface. After entering the first
point, enter the remaining points in a natural clockwise or counterclockwise
order to create a normal 3D face. If you locate all four points on the same
plane, a planar face is created that is similar to a region object. When you
shade or render the object, planar faces are filled.
Invisible Controls which edges of a 3D face are visible, allowing for accurate
modeling of objects with holes. Entering i or invisible before the first point
of an edge makes the edge invisible.
The invisible specification must precede any object snap modes, XYZ filters,
or coordinate input for that edge. You can create a 3D face in which all edges
are invisible. Such a face is a phantom; it does not appear in wireframe
presentations but can hide material in line drawings. 3D faces do appear in
shaded renderings.
You can combine 3D faces to model complex 3D surfaces.

3DFORBIT
Rotates the view in 3D space without constraining roll.
Access Methods
Menu: View Orbit Free Orbit
Pointing device: Press Shift-Ctrl and click the mouse wheel to temporarily
enter 3DFORBIT mode.
32 | Chapter 2 Commands
Shortcut menu: Start any 3D navigation command, right-click in the drawing
area, and click Other Navigation Modes Free Orbit (2).
Summary
Selecting one of more objects before starting this command limits the display
to those objects only.
While the command is active, right-click to display additional options from
a shortcut menu.
3DFORBIT activates a 3D Free Orbit view in the current viewport. If the user
coordinate system (UCS) icon is on, a shaded 3D UCS icon representing the
current UCS appears in the 3D Orbit view. You can view your entire drawing
or select one or more objects before starting the command.
The 3D Free Orbit view displays an arcball, which is a circle divided into four
quadrants by smaller circles. When the Enable Orbit Auto Target option is
deselected in the shortcut menu, the target of the view stays stationary. The
camera location, or point of view, moves around the target. The center of the
arcball, not the center of the objects youre viewing, is the target point. Unlike
3DORBIT (page 40), 3DFORBIT does not constrain the change in view to
prevent roll, the rotation of the view about an axis orthogonal to the plane
of your screen.
NOTE You cannot edit objects while the 3DFORBIT command is active.
Moving your cursor over different parts of the arcball changes the cursor icon,
indicating the direction in which the view rotates. See 3D Free Orbit Cursor
Icons (page 34).
While the command is active, you can access additional 3DORBIT options
from a shortcut menu by right-clicking in the drawing area. See 3D Orbit
Shortcut Menu (page 41).
TIP While in 3D Orbit mode, you can temporarily enter 3D Free Orbit mode by
pressing and holding the Shift key.

Commands | 33
3D Free Orbit Cursor Icons
While using 3D Free Orbit, the cursor changes as it is moved to indicate how
the model will be orbited when clicking and dragging.
View rotation is determined by the placement and appearance of the cursor
as follows:
Sphere Encircled by Two Lines When you move the cursor inside the arcball,
it changes to a small sphere encircled by two lines. If you click and drag in
the drawing area you can move freely around the objects. It works as if your
cursor is grabbing a sphere surrounding the objects and dragging it around
the target point. You can drag horizontally, vertically, and diagonally using
this method.
Circular Arrow When you move the cursor outside the arcball, it becomes a
circular arrow. Clicking outside the arcball and dragging the cursor around
the arcball causes the view to move around an axis that extends through the
center of the arcball, perpendicular to the screen. This is called a roll.
Horizontal Ellipse When you move the cursor over one of the small circles
on the left or right side of the arcball, it becomes a horizontal ellipse. Clicking
and dragging from either of these points rotates the view around the vertical
or Y axis through the middle of the arcball.
Vertical Ellipse When you move the cursor over one of the small circles on
the top or bottom of the arcball, it becomes a vertical ellipse. Clicking and
dragging from either of these points rotates the view around the horizontal
or X axis through the middle of the arcball.

3DMESH
Creates a free-form polygon mesh.
Summary
The mesh density controls the number of facets, and is defined in terms of a
matrix of M and N vertices, similar to a grid consisting of columns and rows.
3DMESH is a legacy method for creating mesh, designed primarily for operation
under program control rather than by manual entry.
To take advantage of smoothing, creasing, and refinement capabilities, use
the MESH (page 617) command.
List of Prompts
The following prompts are displayed.
Size of mesh in M direction Sets the M direction value. Enter a value between
2 and 256.
Size of mesh in N direction Sets the N direction value. Enter a value between
2 and 256.
M times N equals the number of vertices that you must specify.
Location for vertex (0, 0) Sets the coordinate location of the vertex. Enter a
2D or 3D coordinate.
Commands | 35
The location of each vertex in the mesh is defined by m and n, the row and
column indices of the vertex. Defining vertices begins with vertex (0,0). You
must supply the coordinate locations for each vertex in row m before specifying
vertices in row m + 1.
Vertices may be any distance from each other. The M and N orientation of a
mesh depends on the position of its vertices.
3DMESH polygon meshes are always open in both M and N directions. You
can close a mesh with PEDIT (page 767).

58 | Chapter 2 Commands
Summary
Either one, two, or three pairs of source points and definition points can be
specified to move, rotate, or tilt the selected objects, aligning them with points
on another object.
List of Prompts
The following prompts are displayed.
Select objects: Select the objects to align and press Enter
Specify either one (page 59), two (page 59), or three pairs (page 60) of source
points and definition points to align the selected objects.
ALIGN Using One Pair of Points When you select only one source point and
destination point pair, the selected objects move in 2D or 3D from the source
point (1) to the destination point (2).
ALIGN Using Two Pairs of Points When you select two point pairs, you can
move, rotate, and scale the selected objects in 2D or 3D to align with other
objects.
Commands | 59
The first set of source and destination points defines the base point for the
alignment (1, 2). The second set of points defines the angle of rotation (3, 4).
After you enter the second set of points, you are prompted to scale the object.
The distance between the first and second destination points (2, 4) is used as
the reference length to which the object is scaled. Scaling is available only
when you are aligning objects using two point pairs.
NOTE
If you use two source and destination points to perform a 3D alignment on
non-perpendicular working planes, you get unpredictable results.
ALIGN Using Three Pairs of Points When you select three point pairs, you
can move and rotate the selected objects in 3D to align with other objects.
The selected objects move from the source point (1) to the destination point
(2).
The selected object is rotated (1 and 3) so that it aligns with the destination
object (2 and 4).
The selected object is then rotated again (3 and 5) so that it aligns with the
destination object (4 and 6).

AMECONVERT
Converts AME solid models to AutoCAD solid objects.
Summary
The objects you select must be Advanced Modeling Extension (AME) Release
2 or 2.1 regions or solids. All other objects are ignored.
Because of increased accuracy in the new solid modeler, AME models may
look slightly different after conversion. This difference is noticeable where
the previous version of the solid modeler identified the surfaces of two different
shapes as so close as to be considered in the same plane. The new solid
modeler's finer tolerance may interpret these surfaces as being slightly offset.
This phenomenon is most apparent with aligned features such as fillets,
chamfers, and through-holes.
Holes might become blind holes when the new modeler, with its much finer
approximation capability, interprets what was once a through-hole as being
slightly less wide than the solid. Typically, the length of the remaining solid
material is the difference between the tolerance of the previous modeler and
that of the new modeler.
Likewise, updated fillets or chamfers can occasionally be placed slightly below
the surface, creating a hole through the solid, leaving the original shape
unaltered. Also, drawing fillets or chamfers slightly above the original surface
creates an uneven transition between the solid and the fillet or chamfer.

AREA
Calculates the area and perimeter of objects or of defined areas.
Summary
Several commands are available to provide area information including AREA,
MEASUREGEOM (page 613), and MASSPROP (page 597). Alternatively, use
BOUNDARY (page 149) to create a closed polyline or region. Then use LIST
(page 581) or the Properties Inspector (page 832) to find the area.
List of Prompts
The following prompts are displayed.
Specify first corner point (page ?) or [Object (page ?)/Add
Area (page ?)/Subtract Area (page ?)] <Object>: Select an option
The area and perimeter of the specified object displays at the Command prompt
and in the tooltip.
Specify Corner Points
Calculates the area and perimeter defined by specified points. All points must
lie in a plane parallel to the XY plane of the current user coordinate system
(UCS).
A rubberband line from the first specified point to the cursor is displayed.
Once the second point is specified, a line segment and a polygon with green
fill are displayed.
Continue to specify points to define a polygon and then press Enter to
complete the definition of the perimeter. The area to be calculated is
highlighted in green.
If you do not close the polygon, the area is calculated as if a line were drawn
from the last point entered to the first. When the perimeter is calculated, that
line length is added.
Commands | 83
Object
Calculates the area and perimeter of a selected object. You can calculate the
area of circles, ellipses, splines, polylines, polygons, regions, and 3D solids.
NOTE 2D solids (created with the SOLID (page 955) command) do not have an
area reported.
Select object:
If you select an open polyline, the area is calculated as if a line were drawn
from the last point entered to the first. When the perimeter is calculated that
line length is ignored.
The centerline of a wide polyline is used to make area and perimeter
calculations.
The centerline of a wide polyline is used to make area and perimeter (or length)
calculations.
Add Area
Turns on Add mode and keeps a running balance of the total area as you
continue to define areas. You can use the Add Area option to calculate
individual areas and perimeters of defined areas and objects and the total area
of all defined areas and objects.
You can also select to specify the points. A rubberband line from the first
specified point to the cursor is displayed
84 | Chapter 2 Commands
Specify points to define a polygon (3). The area to be added is highlighted in
green. Press Enter. AREA calculates the area and perimeter and returns the
total area of all the areas defined by selecting points or objects since Add mode
was turned on.
If you do not close the polygon, the area is calculated as if a line were drawn
from the last point entered to the first. When the perimeter is calculated, that
line length is added.
Subtract Area
Similar to the Add Area option, but subtracts areas and perimeters. You can
use the Subtract Area option to subtract a specified area from a total area.
You can also specify the area to be subtracted with points. A rubberband line
from the first specified point to the cursor is displayed.

Access Methods
Button
Menu: Modify Array.
Toolbar: Drafting tool set Copy tool group Array flyout
Summary
You can create copies of objects in a regularly spaced rectangular, polar, or
path array.
The DELOBJ (page 1213) system variable controls whether the source objects of
the array are deleted or retained after the array is created.
If you enter -array at the Command prompt, options are displayed (page 87).
List of Prompts
The following prompts are displayed.

Array Objects
-ARRAY
Maintains legacy command line behavior for creating nonassociative, 2D
rectangular or polar arrays.
List of Prompts
The following prompts are displayed.
Select objects: Use an object selection method
Enter the type of array [Rectangular (page ?)/Polar (page
?)] <current>: Enter an option or press Enter
Rectangular
Creates an array of rows and columns of copies of the selected objects.
Enter the number of rows (---) <1>:Enter a nonzero integer or press Enter
Enter the number of columns (|||) <1>:Enter a nonzero integer or press Enter
If you specify one row, you must specify more than one column and vice
versa.
The selected object, or cornerstone element, is assumed to be in the lower-left
corner, and generates the array up and to the right.
The specified distance between the rows and columns includes the
corresponding lengths of the object to be arrayed.
Enter the distance between rows or specify unit cell (---):
Commands | 87
To add rows downward, specify a negative value for the distance between
rows. ARRAY skips the next prompt if you specify two points for the opposite
corners of a rectangle.
Specify the distance between columns (|||):
To add columns to the left, specify a negative value for the distance between
columns. Rectangular arrays are constructed along a baseline defined by the
current snap rotation. This angle is normally 0, so the rows and columns are
orthogonal with respect to the X and Y drawing axes. The Rotate option of
the SNAP (page 952) command changes the angle and creates a rotated array.
The SNAPANG (page 1439) system variable stores the snap rotation angle.
If you specify a large number of rows and columns for the array, it might take
a while to create the copies. By default, the maximum number of array
elements that you can generate in one command is 100,000. The limit is set
by the MAXARRAY setting in the registry. To reset the limit to 200,000, for
example, enter (setenv "MaxArray" "200000") at the Command prompt.
Polar
Creates an array by copying the selected objects around a specified center
point.
Specify center point of array or [Base]: Specify a point or enter b to specify a new
base point
Center Point Creates an array defined by a center point.
Base Specifies a new reference (base) point relative to the selected objects that
will remain at a constant distance from the center point of the array as the
objects are arrayed.
Enter the number of items in the array: Enter a positive integer or press Enter
If you enter a value for the number of items, you must specify either the angle
to fill or the angle between items. If you press ENTER (and do not provide the
number of items), you must specify both.
88 | Chapter 2 Commands
Specify the angle to fill (+=ccw, -=cw) <360>: Enter a positive integer for a
counterclockwise rotation or a negative integer for a clockwise rotation
You can enter 0 for the angle to fill only if you specify the number of items.
If you specify an angle to fill without providing the number of items, or if
you specify the number of items and enter 0 as the angle to fill or press Enter,
the following prompt is displayed:
Angle between items: Specify an angle
If you specified the number of items and entered 0 as the angle to fill or pressed
Enter, ARRAY prompts for a positive or negative value to indicate the direction
of the array:
Angle between items (+=ccw, -=cw): Enter a positive integer for a counterclockwise
rotation or a negative integer for a clockwise rotation
ARRAY determines the distance from the array's center point to a reference
point on the last object selected. The reference point used is the center point
of a circle or arc, the insertion base point of a block or shape, the start point
of text, and one endpoint of a line or trace.
Rotate arrayed objects? <Y>: Enter y or n, or press Enter
In a polar array, the reference point of the last object in the selection set is
used for all objects. If you defined the selection set by using window or crossing
selection, the last object in the selection set is arbitrary. Removing an object
from the selection set and adding it back forces that object to be the last object
selected. You can also make the selection set into a block and replicate it.

-BLOCK
If you enter -block at the Command prompt, the following prompts are
displayed.
List of Prompts
The following prompts are displayed.
Enter block name (page ?) or [?(page ?)]: Enter a name or ?
Block Name
Names the block. The name can have up to 255 characters and can include
letters, numbers, blank spaces, and any special character not used by the
operating system and the program for other purposes if the system variable
EXTNAMES (page 1287) is set to 1.
If you enter the name of an existing block, you are prompted as follows:
Redefine Block Reference By redefining a block, you automatically update
all references to that block. Attributes attached to existing block references
remain unchanged in the drawing. However, new insertions of the block do
not prompt for attributes unless the attribute definitions are included in the
new block definition.
Use the ATTREDEF (page 123) command to update the attributes of an existing
block insert.
Specify Insertion Base Point The point specified as the base point is used
for subsequent insertions of the block. Typically, a base point is the center of
the block or its lower-left corner. The base point is also the point about which
you can rotate the block during insertion. A block with 0 rotation is oriented
according to the UCS in effect when it was created. Entering a 3D point inserts
the block at a specific elevation. Omitting the Z coordinate uses the current
elevation.
Annotative:
Enter a to create an annotative block.
Commands | 147
If you enter yes, the block becomes annotative.
Match Orientation to Layout in Paper Space Viewports If you enter yes,
the blocks orientation in paper space viewports will match the orientation
of the layout.
Select Objects If you specify the insertion base point, you are prompted to
select the objects.
The program defines a block using the objects selected, the insertion base
point, and the name provided, and then erases the selected objects from the
drawing. You can restore the deleted objects by entering the OOPS (page 719)
command immediately after BLOCK.
The insertion base point becomes the origin of the block's coordinate system,
which is parallel to the UCS in effect at the time that you define the block.
When you insert the block into a drawing, its coordinate system is aligned
parallel to the current UCS. Thus, you can insert a block at any orientation
in space by setting the UCS first.
?List Previously Defined Blocks
Lists the block names in the text window.
Enter Blocks to List In the list, external references (xrefs) are indicated with
the notation Xref: resolved.
In addition, externally dependent blocks (blocks in an xref) are indicated with

(1) on an object
Commands | 155
The prompts that are displayed next depend on how you select the object. If
you select the object by using your pointing device, the program both selects
the object and treats the selection point as the first break point. At the next
prompt, you can continue by specifying the second point or overriding the
first point.
Specify second break point or [First point]: Specify the second
break point (2) or enter f
Second Break Point Specifies the second point to use to break the object.
First Point Overrides the original first point with the new point that you
specify.
Specify first break point:
Specify second break point:
The portion of the object is erased between the two points that you specify.
If the second point is not on the object, the nearest point on the object is
selected; therefore, to break off one end of a line, arc, or polyline, specify the
second point beyond the end to be removed.
To split an object in two without erasing a portion, enter the same point for
both the first and second points. You can do this by entering @ to specify the
second point.
Lines, arcs, circles, polylines, ellipses, splines, donuts, and several other object
types can be split into two objects or have one end removed.
The program converts a circle to an arc by removing a piece of the circle
starting counterclockwise from the first to the second point.

Summary
The distances and angles that you specify are applied in the order that you
select the objects.
You can chamfer lines, polylines, rays, and xlines.
182 | Chapter 2 Commands
You can also chamfer 3D solids and surfaces. If you select a mesh to chamfer,
you can choose to convert it to a solid or surface before completing the
operation.
List of Prompts
The following prompts are displayed.

Select first line (page ?) or [Undo (page ?)/Polyline (page
?)/Distance (page ?)/Angle (page ?)/Trim (page ?)/mEthod
(page ?)/Multiple (page ?)/eXpression (page 185)]: Use an
object selection method or enter an option
First Line
Specifies the first of two edges required to define a 2D chamfer, or the edge
of a 3D solid to chamfer.
If you select lines or polylines, their lengths adjust to accommodate the
chamfer line. You can hold down Shift while selecting the objects to override
the current chamfer distances with a value of 0.
If the selected objects are line segments of a 2D polyline, they must be adjacent
or separated by no more than one segment. If they're separated by another
polyline segment, CHAMFER deletes the segment that separates them and
replaces it with the chamfer.
If you select an edge on a 3D solid, you must indicate which one of the two
surfaces adjacent to the edge is the base surface.
Enter Surface Selection Option Entering o or pressing Enter sets the selected
surface as the base surface. Entering n selects either of the two surfaces adjacent
to the selected edge.
After you select the base surface and the chamfer distances, select the edges
of the base surface to chamfer. You can select edges individually or all the
edges at once.
Edge Selects an individual edge to chamfer.
Commands | 183
Loop Switches to Edge Loop mode.
Edge Loop Selects all edges on the base surface.
Undo
Reverses the previous action in the command.
Polyline
Chamfers an entire 2D polyline.
The intersecting polyline segments are chamfered at each vertex of the polyline.
Chamfers become new segments of the polyline.
If the polyline includes segments that are too short to accommodate the
chamfer distance, those segments are not chamfered.
Distance
Sets the distance of the chamfer from the endpoint of the selected edge.
If you set both distances to zero, CHAMFER extends or trims the two lines so
they end at the same point.
184 | Chapter 2 Commands
Angle
Sets the chamfer distances using a chamfer distance for the first line and an
angle for the second line.
Trim
Controls whether CHAMFER trims the selected edges to the chamfer line
endpoints.
NOTE Trim sets the TRIMMODE (page 1473) system variable to 1; No Trim sets
TRIMMODE to 0.
If the TRIMMODE system variable is set to 1, CHAMFER trims the intersecting
lines to the endpoints of the chamfer line. If the selected lines do not intersect,
CHAMFER extends or trims them so that they do. If TRIMMODE is set to 0,
the chamfer is created without trimming the selected lines.
Method
Controls whether CHAMFER uses two distances or a distance and an angle to
create the chamfer.
Multiple
Chamfers the edges of more than one set of objects.

Saturation, and Luminance (HSL) color model or the Red, Green, and Blue
(RGB) color model. Over sixteen million colors are available when using true
color functionality. The options available on the True Color tab are dependent
on whether the HSL or RGB color model is specified.
List of Options
The following options are displayed.
HSL Color Model
Specifies the HSL color model for selecting colors.
Hue, saturation, and luminance are properties of colors. By manipulating the
values of these properties, you can specify a wide range of colors.
Hue (H)
Specifies the hue of a color. Hues represent a specific wavelength of light
within the visible spectrum. To specify a hue, use the color spectrum or specify
a value in the Hue box. Adjusting this value affects the RGB value. Valid hue
values are from 0 to 360 degrees.
Commands | 201
Saturation (S)
Specifies the purity of a color. High saturation causes a color to look more
pure while low saturation causes a color to look washed-out. To specify color
saturation, use the color spectrum or specify a value in the Saturation box.
Adjusting this value affects the RGB value. Valid saturation values are from 0
to 100%.
Luminance (L)
Specifies the brightness of a color. To specify color luminance, use the color
slider or specify a value in the Luminance box. Valid luminance values are
from 0 to 100%. A value of 0% represents the color black, 100% represents
white, and 50% represents the optimal brightness for the color. Adjusting this
value also affects the RGB value.
Color Spectrum Specifies the hue and purity of a color. To specify a hue,
move the crosshairs from side to side over the color spectrum. To specify color
saturation, move the crosshairs from top to bottom over the color spectrum.
Color Slider Specifies the brightness of a color. To specify color luminance,
adjust the bar on the color slider or specify a value in the Luminance box.
RGB Color Model
Specifies the RGB color model for selecting colors. The options available on
the True Color tab are dependent on whether the HSL or RGB color model is
specified.
Colors can be broken down into components of red, green, and blue. The
values specified for each component represent the intensity of the red, green,
and blue components. The combination of these values can be manipulated
to create a wide range of colors.
Red (R)
Specifies the red component of a color. Adjust the slider on the color bar or
specify a value from 1 to 255 in the Red box. If this value is adjusted, it will
be reflected in the HSL color mode values.
Green (G)
Specifies the green component of a color. Adjust the slider on the color bar
or specify a value from 1 to 255 in the Green box. If this value is adjusted, it
will be reflected in the HSL color mode values.
Blue (B)
202 | Chapter 2 Commands
Specifies the blue component of a color. Adjust the slider on the color bar or
specify a value from 1 to 255 in the Blue box. If this value is adjusted, it will
be reflected in the HSL color mode values.
Color
Specifies the RGB color value. This option is updated when changes are made
to HSL or RGB options. You can also edit the RGB value directly using the
following format: 000,000,000.
True Color Stored as RGB
Indicates the value for each RGB color component.

CONVERT
Optimizes 2D polylines and associative hatches created in AutoCAD Release
13 or earlier.
Sumary
Hatches are not updated automatically when a drawing from a previous release
is opened in Release 14 or later. Information about the rotation of a hatch
pattern may not be updated properly if you have changed the UCS since
creating the hatch. When updating hatches with CONVERT, it is recommended
that you use the Select option so that you can check your results.
In most cases, you do not need to update polylines with CONVERT. By default,
the PLINETYPE (page 1396) system variable specifies that polylines are updated
automatically when you open an older drawing. Polylines may be created in
the old format by third-party applications, and they may be contained in an
older drawing that was inserted as a block and then exploded.
NOTE
Polylines containing curve-fit or splined segments always retain the old format,
as do polylines that store extended object data on their vertices. Editing
commands make no distinction between the two formats.

Specify dimension arc line location (page 277) or [Mtext (page
277)/Text (page 277)/Angle (page 277)/Quadrant (page 278)]:
Arc Selection Uses points on the selected arc as the defining points for a
three-point angular dimension. The center of the arc is the angle vertex. The
arc endpoints become the origin points of the extension lines.
Commands | 275
The dimension line is drawn as an arc between the extension lines. The
extension lines are drawn from the angle endpoints to the intersection of the
dimension line.
Circle Selection Uses the selection point (1) as the origin of the first extension
line. The center of the circle is the angle vertex.
The second angle endpoint is the origin of the second extension line and does
not have to lie on the circle.
Line Selection Defines the angle using two lines.
The program determines the angle by using each line as a vector for the angle
and the intersection of the lines for the angle vertex. The dimension line spans
the angle between the two lines. If the dimension line does not intersect the
lines being dimensioned, extension lines are added as needed to extend one
or both lines. The arc is always less than 180 degrees.
Three-Point Specification Creates a dimension based on three points you
specify.
The angle vertex can be the same as one of the angle endpoints. If you need
extension lines, the endpoints are used as origin points.

In model space, changes in X, Y, and Z component distances and angles are
measured in 3D relative to the current UCS.
In paper space, distances are normally reported in 2D paper space units.
However, when using object snaps on model space objects that are displayed
in a single viewport, distances are reported as 2D model space distances
projected onto a plane parallel to your screen.

Under Objects Moves the selected objects below the specified reference objects.
Front Moves the selected objects to the top of the order of objects in the
drawing.
Back Moves the selected objects to the bottom of the order of objects in the
drawing.
When you change the draw order (display and plotting order) of multiple
objects, the relative draw order of the selected objects is maintained.
By default, when you create new objects from existing ones (for example,
FILLET or PEDIT), the new objects are assigned the draw order of the original
object you selected first. By default, while you edit an object (for example,
MOVE or STRETCH), the object is displayed on top of all objects in the drawing.
When you are finished editing, your drawing is partially regenerated so that
the object is displayed according to its correct draw order. This can result in
some edit operations taking slightly longer. You can use DRAWORDERCTL
(page 1273) to change the default draw order settings.

Object Selection
Specifies objects to use in the preview image as you change views. Selecting
too many objects slows image dragging and updating.
DVIEWBLOCK
If you press Enter at the Select Objects prompt, DVIEWBLOCK displays a
preview image. You can create your own DVIEWBLOCK block in a 1 unit by
Commands | 385
1 unit by 1 unit area, with its origin at the lower-left corner. The following
illustration shows an example of using the default DVIEWBLOCK to set the
view (moving the graphics cursor adjusts the view).
Point Specification
Rolls the view under the camera. The point you select with your pointing
device is a start point for the dragging operation. Your viewing direction
changes about the target point as you move the pointing device.
The angles must be positive. The direction angle indicates the front of the
view, and the magnitude angle determines how far the view rolls.
Camera
Specifies a new camera position by rotating the camera about the target point.
Two angles determine the amount of rotation.
Camera Location Sets the camera's position based on the specified point.
Enter Angle from the XY Plane Sets the camera's position at an angle above
or below the XY plane. An angle of 90 degrees looks down from above, and
an angle of -90 looks up from below. A camera angle of 0 degrees places the
camera parallel to the XY plane of the user coordinate system (UCS).
Toggle (Angle In) Switches between two angle input modes. Entering an angle
at the Command prompt locks the cursor movement so you see only the
positions available for that angle. Toggle unlocks the cursor movement for
the angle, and you can use the cursor to rotate the camera.
386 | Chapter 2 Commands
Enter Angle in XY Plane from X Axis Sets the position at an angle in the
XY plane relative to the X axis of the current UCS. This angle measures from
-180 to 180 degrees. A rotation angle of 0 degrees looks down the X axis of
the UCS toward the origin.
The illustration shows the camera rotating to the left from its initial position,
leaving its angle from the XY plane unchanged.
Toggle (Angle From) Switches between two angle input modes. Entering an
angle at the Command prompt locks the cursor movement so you see only
the positions available for that angle. Toggle unlocks the cursor movement
for the angle, and you can use the cursor to rotate the camera.
Target
Specifies a new position for the target by rotating it around the camera. The
effect is like turning your head to see different parts of the drawing from one
vantage point. Two angles determine the amount of rotation.
Enter Angle from the XY Plane Enter Angle from the XY Plane (page 386)
Toggle (Angle In) Toggle (Angle In) (page 386)
Enter Angle in XY Plane from X Axis Enter Angle in XY Plane from X Axis
(page 387)The illustration shows the effect of moving the target point from
left to right, leaving its angle from the XY plane unchanged.
Commands | 387
Toggle (Angle From) Toggle (Angle From) (page 387)
Distance
Moves the camera in or out along the line of sight relative to the target. This
option turns on perspective viewing, which causes objects farther from the
camera to appear smaller than those closer to the camera. A special perspective
icon replaces the coordinate system icon. You are prompted for the new
camera-to-target distance.
A slider bar along the top of the drawing area is labeled from 0x to 16x, with
1x representing the current distance. Moving the slider bar to the right
increases the distance between camera and target. Moving it to the left
decreases that distance. To turn off perspective viewing, click the Off option
from the main DVIEW prompt.
If the target and camera points are close together, or if you specify a
long-focal-length lens, you might see very little of your drawing when you
specify a new distance. If you see little or none of your drawing, try the
maximum scale value (16x) or enter a large distance. To magnify the drawing
without turning perspective viewing on, use the Zoom option of DVIEW.
388 | Chapter 2 Commands
The illustration shows the effect of moving the camera along the line of sight
relative to the target, where the field of view remains constant.
Points
Locates the camera and target points using X,Y,Z coordinates. You can use
XYZ point filters.
To help you define a new line of sight, a rubber-band line is drawn from the
current camera position to the crosshairs. You are prompted for a new camera
location.
A rubber-band line connects the target point to the crosshairs to help you
place the camera relative to the target. The illustration shows the change in
view as you swap the camera and target points. Lens and distance settings are
the same in each case.
Commands | 389
For information about entering direction and magnitude angles, see Point
Specification.
Pan
Shifts the image without changing the level of magnification.
Zoom
If perspective viewing is off, dynamically increases or decreases the apparent
size of objects in the current viewport.
A slider bar along the top of the drawing area is labeled from 0x to 16x, with
1x representing the current scale. Moving the slider bar to the right increases
the scale. Moving it to the left decreases the scale.
If perspective viewing is on, Zoom adjusts the camera lens length, which
changes the field of view and causes more or less of the drawing to be visible
at a given camera and target distance. The default lens length is 50mm,
simulating what you'd see with a 35mm camera and a 50mm lens. Increasing
the lens length is similar to switching to a telephoto lens. Decreasing the lens
length widens the field of view, as with a wide-angle lens.
A slider bar along the top of the drawing area is labeled from 0x to 16x, with
1x representing the current lens length. Moving the slider bar to the right
increases the lens length. Moving it to the left decreases the lens length.
390 | Chapter 2 Commands
Twist
Twists or tilts the view around the line of sight. The twist angle is measured
counterclockwise, with 0 degrees to the right.
Clip
Clips the view, obscuring portions of the drawing that are behind or in front
of the front clipping plane. The front and back clipping planes are invisible
walls that you can position perpendicular to the line of sight between the
camera and target.
Back Obscures objects located behind the back clipping plane.
Distance from Target. Positions the back clipping plane and turns on
back clipping. A positive distance places the clipping plane between the
target and the camera. A negative distance places it beyond the target. You
can use the slider bar to drag the clipping plane.
On. Turns on back clipping at the current clipping distance.
Off. Turns off back clipping.
Commands | 391
Front Obscures objects located between the camera and the front clipping
plane.
Distance from Target.Positions the front clipping plane and turns on
front clipping. A positive distance places the clipping plane between the
target and the camera. A negative distance places it beyond the target. You
can use the slider bar to drag the clipping plane.
Eye. Positions the front clipping plane at the camera.
On. Turns on front clipping. This option is available only when perspective
viewing is off.
Off. Turns off front clipping. This option is available only when perspective
viewing is off.
Off Turns off front and back clipping. If perspective viewing is on, front
clipping remains on at the camera position.
Hide
Suppresses hidden lines on the selected objects to aid in visualization. Circles,
solids, traces, regions, wide polyline segments, 3D faces, polygon meshes, and
the extruded edges of objects with nonzero thickness are considered to be
opaque surfaces that hide objects.This hidden line suppression is quicker than
that performed by HIDE (page 506), but it cannot be plotted.
Off
Turns off perspective viewing. The Distance option turns on perspective
viewing.
Undo
Reverses the effects of the last DVIEW action. You can undo multiple DVIEW
operations.

Toolbar: Drafting tool set Closed Shapes tool group Ellipse flyout
Center
Menu: Draw Ellipse Center
Summary
The first two points of the ellipse determine the location and length of the
first axis. The third point determines the distance between the center of the
ellipse and the end point of the second axis.
List of Prompts
The following prompts are displayed.
Specify axis endpoint (page ?) of ellipse or [Arc (page
?)/Center (page ?)/Isocircle (page ?)]: Specify a point or enter
an option
Axis Endpoint
Defines the first axis by its two endpoints. The angle of the first axis determines
the angle of the ellipse. The first axis can define either the major or the minor
axis of the ellipse.
Distance to Other Axis Defines the second axis using the distance from the
midpoint of the first axis to the endpoint of the second axis (3).
Rotation Creates the ellipse by appearing to rotate a circle about the first axis.
Commands | 403
Move the crosshairs around the center of the ellipse and click. If you enter a
value, the higher the value, the greater the eccentricity of the ellipse. Entering
0 defines a circular ellipse.
Arc
Creates an elliptical arc.
The angle of the first axis determines the angle of the elliptical arc. The first
axis can define either the major or the minor axis depending on its size.
The first two points of the elliptical arc determine the location and length of
the first axis. The third point determines the distance between the center of
the elliptical arc and the endpoint of the second axis. The fourth and fifth
points are the start and end angles.
Axis Endpoint Defines the start point of the first axis.
Rotation Defines the major to minor axis ratio of the ellipse by rotating a
circle about the first axis. The higher the value from 0 through 89.4 degrees,
the greater the ratio of minor to major axis. Values between 89.4 degrees and
90.6 degrees are invalid because the ellipse would otherwise appear as a straight
line. Multiples of these angle values result in a mirrored effect every 90 degrees.
Start Angle Defines the first endpoint of the elliptical arc. The Start Angle
option toggles from Parameter mode to Angle mode. The mode controls how
the ellipse is calculated.
404 | Chapter 2 Commands
Parameter Requires the same input as Start Angle, but creates the elliptical
arc using the following parametric vector equation:
p(u) = c + a * cos(u) + b * sin(u)
where c is the center of the ellipse and a and b are its major and minor axes,
respectively.
End Parameter: Defines the end angle of the elliptical arc by using a
parametric vector equation. The Start Parameter option toggles from Angle
mode to Parameter mode. The mode controls how the ellipse is calculated.
Angle: Defines the end angle of the elliptical arc. The Angle option toggles
from Parameter mode to Angle mode. The mode controls how the ellipse
is calculated.
Included Angle: Defines an included angle beginning at the start angle.
Center
Creates an ellipse using a center point, the endpoint of the first axis, and the
length of the second axis. You can specify the distances by clicking a location
at the desired distance or by entering a value for the length.
Distance to Other Axis Defines the second axis as the distance from the center
of the ellipse, or midpoint of the first axis, to the point you specify.
Rotation Creates the ellipse by appearing to rotate a circle about the first axis.
Move the crosshairs around the center of the ellipse and click. If you enter a
value, the higher the value, the greater the eccentricity of the ellipse. Entering
0 defines a circle.
Commands | 405
Isocircle
Creates an isometric circle in the current isometric drawing plane.
NOTE The Isocircle option is available only when you set the Style option of SNAP
(page 952) to Isometric.
Radius Creates a circle using a radius you specify.

EXPLODE
Breaks a compound object into its component objects.
Access Methods
Button
Toolbar: Drafting tool set Explode and Erase tool group Explode
Menu: Modify Explode
Summary
Explodes a compound object when you want to modify its components
separately. Objects that can be exploded include blocks, polylines, and regions,
among others.
Commands | 407
The color, linetype, and lineweight of any exploded object might change.
Other results differ depending on the type of compound object you're
exploding. See the following list of objects that can be exploded and the results
for each.
To explode objects and change their properties at the same time, use XPLODE
(page 1149).
NOTE If you're using a script or an ObjectARX® function, you can explode only
one object at a time.
2D and Lightweight Polyline Discards any associated width or tangent
information. For wide polylines, the resulting lines and arcs are placed along
the center of the polyline.
3D Polyline Explodes into line segments. Any linetype assigned to the 3D
polyline is applied to each resulting line segment.
3D Solid Explodes planar faces into regions. Nonplanar faces explode into
surfaces.
Annotative Objects Explodes the current scale representation into its
constituent parts which are no longer annotative. Other scale representations
are removed.
Arc If within a nonuniformly scaled block, explodes into elliptical arcs.
408 | Chapter 2 Commands
Block Removes one grouping level at a time. If a block contains a polyline or
a nested block, exploding the block exposes the polyline or nested block object,
which must then be exploded to expose its individual objects.
Blocks with equal X, Y, and Z scales explode into their component objects.
Blocks with unequal X, Y, and Z scales (nonuniformly scaled blocks) might
explode into unexpected objects.
When nonuniformly scaled blocks contain objects that cannot be exploded,
they are collected into an anonymous block (named with a *E prefix) and
referenced with the nonuniform scaling. If all the objects in such a block
cannot be exploded, the selected block reference will not be exploded. Body,
3D Solid, and Region entities in a nonuniformly scaled block cannot be
exploded.
Exploding a block that contains attributes deletes the attribute values and
redisplays the attribute definitions.
Blocks inserted with MINSERT (page 643) and external references (xrefs) and
their dependent blocks cannot be exploded.
Body Explodes into a single-surface body (nonplanar surfaces), regions, or
curves.
Circle If within a nonuniformly scaled block, explodes into ellipses.
Leaders Explodes into lines, splines, solids (arrow heads), block inserts (arrow
heads, annotation blocks), multiline text, or tolerance objects, depending on
the leader.
Mesh Objects Explodes each face into a separate 3D face object. Color and
materials assignments are retained.
Multiline Text Explodes into text objects.
Multiline Explodes into lines and arcs.
Polyface Mesh Explodes one-vertex meshes into a point object. Two-vertex
meshes explode into a line. Three-vertex meshes explode into 3D faces.
Region Explodes into lines, arcs, or splines.

EXTRUDE
Creates a 3D solid or surface by extending the dimensions of an object.
Access Methods
Button
Toolbar: Modeling tool set Solids - Create tool group Extrude
Menu: Draw 3D Modeling Extrude
Summary
When extruded, open curves create surfaces and closed curves create solids or
surfaces, depending on the specified mode. For surfaces, use the SURFACEMOD-
ELINGMODE (page 1453) system variable to control whether the surface use a
NURBS surface or a procedural surface. Use the SURFACEASSOCIATIVITY (page
1452) system variable to control whether procedural surfaces are associative. To
extrude meshes, use the MESHEXTRUDE (page 632) command.
Commands | 423
You can extrude either an open or closed object to create a 3D surface or solid.
If you extrude a surface, you will create a regular surface or a NURBS surface
depending on how the SURFACEMODELINGMODE (page 1453) system variable
is set. To extrude meshes, use the MESHEXTRUDE (page 632) command.
The DELOBJ (page 1213) system variable controls whether the object(s) and path
(if selected) are automatically deleted when the solid or surface is created or
whether you are prompted to delete the object(s) and path.
You can use the following objects and subobjects with EXTRUDE:

List of Prompts
The following prompts are displayed.
Objects to Extrude Specifies the objects to extrude.
NOTE
Select face and edge subobjects by pressing Ctrl while you select them.
Mode Controls whether the extruded object is a solid or a surface. Surfaces
are extruded as either NURBS surfaces or procedural surfaces, depending on
the SURFACEMODELINGMODE (page 1453) system variable.
Height of extrusion Extrudes objects along the positive Z axis of the object's
coordinate system if you enter a positive value. If you enter a negative value,
the objects are extruded along the negative Z axis. Objects do not have to be
parallel to the same plane. If all objects are on a common plane, the objects
are extruded in the direction of the normal of the plane.
By default, planar objects are extruded in the direction of the objects normal.
Direction Specifies the length and direction of the extrusion with two specified
points. (The direction cannot be parallel to the plane of the sweep curve
created by the extrusion.)
Start point of direction. Specifies the first point in the direction vector.
End point of direction. Specifies the second point in the direction
vector.
426 | Chapter 2 Commands
Path Specifies the extrusion path based on a selected object. The path is moved
to the centroid of the profile. Then the profile of the selected object is extruded
along the chosen path to create solids or surfaces.
NOTE
Select face and edge subobjects by pressing Ctrl while you select them.
The path should not lie on the same plane as the object, nor should the path
have areas of high curvature.
The extrusion starts from the plane of the object and maintains its orientation
relative to the path.
If the path contains segments that are not tangent, the program extrudes the
object along each segment and then miters the joint along the plane bisecting
the angle formed by the segments. If the path is closed, the object should lie
on the miter plane. This allows the start and end sections of the solid to match
up. If the object is not on the miter plane, the object is rotated until it is on
the miter plane.
Objects with multiple loops are extruded so that all of the loops appear on
the same plane at the end section of the extruded solid.
Taper angle Specifies the taper angler for the extrusion.
Positive angles taper in from the base object. Negative angles taper out. The
default angle, 0, extrudes a 2D object perpendicular to its 2D plane. All selected
objects and loops are tapered to the same value.
Specifying a large taper angle or a long extrusion height can cause the object
or portions of the object to taper to a point before reaching the extrusion
height.
Commands | 427
Individual loops of a region are always extruded to the same height.
When an arc is part of a tapered extrusion, the angle of the arc remains
constant, and the radius of the arc changes.
Angle of taper. Specifies the taper between -90 and +90 degrees.
Specify two points. Specifies the taper angle based on two specified
points. The taper angle is the distance between the two specified points.
Drag the cursor horizontally to specify and preview the taper angle. You can
also drag the cursor to adjust and preview the height of the extrusion. The
dynamic input origin should be placed on the extruded shape, on the
projection of the point to the shape.
When you select the extruded object, the position of the taper grip is the
correspondent point of the dynamic input origin on the top face of the
extrusion.
Expression Enter a formula or equation to specify the extrusion height. See
Constrain a Design with Formulas and Equations.

Select an edge or [Chain/Loop/Radius]: Select edge(s), enter c, l, or r
Edge
Selects a single edge. You can continue to select single edges until you press
Enter.
If you select three or more edges that converge at a vertex to form the corner
of a box, FILLET computes a vertex blend that is part of a sphere if the three
incident fillets have the same radii.
Chain
Changes from selection of single edges to selection of sequential tangent edges,
called a chain selection.
434 | Chapter 2 Commands
Edge Chain Selects a tangential sequence of edges when you select a single
edge. For example, if you select an edge on the top of a 3D solid box, FILLET
also selects the other tangential edges on the top.
Edge Switches to a single-edge selection mode.
Loop

Attenuation
Enter an option to change [attenuation Type/Use limits/attenuation start
Limit/attenuation End limit/eXit]<eXit>:
Attenuation Type Controls how light diminishes over distance. The farther
away an object is from a spotlight, the darker the object appears. Attenuation
is also known as decay.
None. Sets no attenuation. Objects far from the spotlight are as bright as
objects close to the light.
Inverse Linear. Sets attenuation to be the inverse of the linear distance
from the light. For example, at a distance of 2 units, light is half as strong
as at the spotlight; at a distance of 4 units, light is one quarter as strong.
The default value for inverse linear is half the maximum intensity.
Inverse Squared. Sets attenuation to be the inverse of the square of the
distance from the light. For example, at a distance of 2 units, light is one
quarter as strong as at the spotlight; at a distance of 4 units, light is one
sixteenth as strong.
Use Limits Specifies whether to use limits or not.
Attenuation Start Limit Specifies the point where light starts as an offset
from the center of the light. The default is 0.
446 | Chapter 2 Commands
Attenuation End Limit Specifies the point where light ends as an offset from

NOTE This option is available only in the Hatch Edit dialog box (page 497) and
replaces the View Selections option.
When you select an associative hatch, a single, circular grip called the control
grip is displayed. No boundary grips are displayed because the boundaries of
an associative hatch can be modified only by changing its associated boundary
objects. Use the Select Boundary Objects option to select and grip-edit the
boundary objects.
To modify the boundaries of a nonassociative hach, you modify the boundaries
of the hatch object itself. Thus, when you select a nonassociative hatch, both
the control grip and the boundary grips are displayed.

HIDE
Regenerates a 3D wireframe model with hidden lines suppressed.
Access Methods
Menu: View Hide
Summary
When you use VPOINT (page 1114), DVIEW (page 385), or VIEW (page 1104) to
create a 3D view of your 2D drawing, a wireframe is displayed in the current
viewport. All lines are present, including those hidden by other objects. HIDE
eliminates the hidden lines from the screen.
HIDE considers the following to be opaque surfaces that hide objects: circles,
solids, traces, text, regions, wide polyline segments, 3D faces, polygon meshes,
and the extruded edges of objects with nonzero thickness.
If they are extruded, circles, solids, traces, and wide polyline segments are
treated as solid objects with top and bottom faces. You cannot use HIDE on
objects whose layers have been frozen; however, you can use HIDE on objects
whose layers have been turned off.
To hide text created with MTEXT or TEXT, the HIDETEXT (page 1318) system
variable must be set to 1 or the text must be assigned a thickness value.
When using the HIDE command, if the INTERSECTIONDISPLAY (page 1342)
system variable is on, face-to-face intersections of 3D surfaces are displayed
as polylines.
The 3D Hidden visual style does not honor the setting of
INTERSECTIONDISPLAY.
506 | Chapter 2 Commands
If the DISPSILH (page 1254) system variable is on, HIDE displays 3D solid objects
with silhouette edges only. It won't show the internal edges produced by
objects that have facets.
If the HIDETEXT system variable is off, HIDE ignores text objects when
producing the hidden view. Text objects are always displayed regardless of
whether they are obscured by other objects, and objects obscured by text
objects are unaffected.

default. To avoid errors when entering an image name, it is recommended
that you specify both the image name and the file name as follows:
imagename=path name/long file name.bmp
or
imagename="path name/long file name.bmp"
If you enter a valid image name without a file extension, the program searches
for the file in this order: first, an existing image definition in the drawing,
and second, an image file in the folders in order of the search path. The
program searches for all the image files with the specified name, regardless of
extension, and uses the first name found. If no image name or image file is
found, the message Image Not Found is displayed and the prompt is repeated.

If you select a single image, the default values for Brightness, Contrast, and
Fade are the current property settings of the image. If you select multiple
images, the default values for Brightness, Contrast, and Fade are 50, 50, and
0, respectively.
Contrast Controls the contrast, and indirectly, the fading effect of the image.
The greater the value, the more each pixel is forced to its primary or secondary
color.
Brightness Controls the brightness, and indirectly the contrast, of the image.
The greater the value, the brighter the image and the more pixels that become
white when you increase contrast.
Fade Controls the fading effect of the image. The greater the value, the more
the image blends with the current background color. A value of 100 blends
the image completely into the background. Changing the screen background
color causes the image to fade to the new color. In plotting, the background
color for fade is white.

-INTERFERE
Summary
INTERFERE highlights all interfering 3D solids and displays the number of
objects selected and the number of interfering pairs.
If you define a single selection set, INTERFERE checks all the solids in the set
against one another. If you define two selection sets, INTERFERE checks the
solids in the first selection set against those in the second selection set. If you
include the same 3D solids in both selection sets, INTERFERE considers the
3D solid part of the first selection set and ignores it in the second selection
set.
List of Prompts
The following prompts are displayed.
Check for interferences between 2 sets of objects or within
1 set of objects...
Select first set of objects or [Nested selection (page ?)]:
Use an object selection method or enter an option

Creates a 3D solid, surface, or 2D region from overlapping solids, surfaces, or
regions.
Access Methods
Button
Toolbar: Modeling tool set Solids - Edit tool group Booleans flyout
Intersect
Menu: Modify Solid Editing Intersect
Summary
With INTERSECT, you can create a 3D solid from the common volume of two
or more existing 3D solids, surfaces, or regions. If you select a mesh, you can
convert it to a solid or surface before completing the operation.
You can extrude 2D profiles and then intersect them to create a complex
model efficiently.
Commands | 531
The selection set can contain regions, solids, and surfaces that lie in any
number of arbitrary planes. INTERSECT divides the selection set into subsets
and tests for intersections within each subset. The first subset contains all the
solids and surfaces in the selection set. The second subset contains the first
selected region and all subsequent coplanar regions. The third subset contains
the next region that is not coplanar with the first region and all subsequent
coplanar regions, and so on until all regions belong to a subset.

JOIN
Joins the endpoints of linear and curved objects to create a single object.
Access Methods
Button
Toolbar: Drafting tool set Modify tool group (expanded) Join
Menu: Modify Join
Summary
Combines a series of finite linear and open curved objects at their common
endpoints to create a single 2D or 3D object. The type of object that results
depends on the types of objects selected, the type of object selected first, and
whether the objects are coplanar.
534 | Chapter 2 Commands
You can join objects in different planes if the source object is a spline or a 3D
polyline. Each type of object has additional restrictions.
NOTE
Construction lines, rays, and closed objects cannot be joined.
List of Prompts
The following prompts are displayed.
Select source object or multiple objects to join at once:
Select lines, polylines, 3D polylines, arcs, elliptical arcs, helixes, or splines.
Source Object
Specifies a single source object to which you can join other objects. Press Enter
after selecting the source object to begin selecting the objects to join. The
following rules apply for each type of source object:
Line Only line objects can be joined to the source line. The line objects must
all be collinear, but can have gaps between them.
Polyline Lines, polylines, and arcs can be joined to the source polyline. All
objects must be contiguous and coplanar. The resulting object is a single
polyline.
3D Polyline Any linear or curved object can be joined to the source 3D
polyline. All the objects must be contiguous, but can be noncoplanar. The
resulting object is either a single 3D polyline or a single spline, depending on
whether you are joining to a linear or a curved object respectively.
Arc Only arcs can be joined to the source arc. All the arc objects must have
the same radius and center point, but can have gaps between them. The arcs
are joined in a counterclockwise direction starting from the source arc.
The Close option converts the source arc into a circle.
Commands | 535
Elliptical Arc Only elliptical arcs can be joined to the source elliptical arc.
The elliptical arcs must be coplanar and have the same major and minor axes,
but can have gaps between them. The elliptical arcs are joined counterclockwise
starting from the source elliptical arc.
The Close option converts the source elliptical arc into an ellipse.
Helix Any linear or curved object can be joined to the source helix. All objects
must be contiguous, but can be noncoplanar. The resulting object is a single
spline.
Spline Any linear or curved object can be joined to the source spline. All
objects must be contiguous, but can be noncoplanar. The resulting object is
a single spline.
Multiple Objects to Join at Once
Joins multiple objects without specifying a source object. The rules and
resulting object types are as follows:
A line object results from joining collinear lines. The lines can have gaps
between their endpoints.
An arc or circle object results from joining coplanar arcs with the same
center point and radius. The arcs can have gaps between their endpoints.
Lengthening occurs in a counterclockwise direction. A circle object results
if the joined arcs form a complete circle.
A spline object results from joining splines, elliptical arcs, or helixes
together, or to other objects. The objects can be noncoplanar.
A polyline object results from joining coplanar lines, arcs, polylines, or 3D
polylines.
A 3D polyline results from joining noncoplanar objects other than curved
objects.

Command entry: 'layer for transparent use
Summary
The Layers Palette (page 538) is displayed.
If you enter -layer at the Command prompt, options are displayed (page 551).
Commands | 537
Use layers to control the visibility of objects and to assign properties such as
color and linetype. Objects on a layer normally assume the properties of that
layer. However, you can override any layer property of an object. For example,
if an objects color property is set to BYLAYER, the object displays the color
of that layer. If the objects color is set to Red, the object displays as red,
regardless of the color assigned to that layer.

Layers Palette
Displays a list of the layers in the drawing and their properties.
538 | Chapter 2 Commands
Summary
You can add, delete, and rename layers, change their properties, set property
overrides for layout viewports, or add layer descriptions and apply changes
in realtime.
When switching layouts or when activating a viewport on named (paper space)
layout, the Layers palette is updated and displays the current state of the layer
properties in the current space.
List of Options
The following options are displayed.
Layer Drop-down
Displays the current layer and its color, along with some of its common
properties. Click the drop-down list to adjust a layers On/Off, Lock/Unlock,
or Thaw/Freeze state. You can also select a layer to set it current.

layers in the current drawing.
Layer List
Displays the layers and layer groups in the current drawing and their properties.
Click in the columns for a layer to change its properties.
Status Indicates the status of the layer: layer in use, empty layer, or current
layer.
Object Selection Indicates if the layer is assigned to an object that is currently
selected. Objects must be selected when no command is active.
Visibility Indicates if the layer is on and off. When a layer is on, it is visible
and available for plotting. When a layer is off, it is invisible and not plotted,
even if Plot is on.
Description Text string that describes the layer.
Name Displays the name of the layer.
Press Fn-F2 to enter a new name or click over the name when the layer is
highlighted.
Freeze Indicates if the layer is frozen or thawed.
Layers can be frozen in all layouts and viewports, including the Model layout.
You can freeze layers to speed up ZOOM (page 1153), PAN (page 763), and many
other operations; improve object selection performance; and reduce
regeneration time for complex drawings.
Objects on frozen layers are not displayed, plotted, hidden, rendered, or
regenerated.
540 | Chapter 2 Commands
Freeze the layers you want to be invisible for long periods. If you plan to switch
visibility settings frequently, use the On/Off property to avoid regenerating
the drawing. You can freeze a layer in all viewports, in the current layout
viewport, or in new layout viewports as they are created.
Lock Indicates if the layer is locked or unlocked. Objects on a locked layer
cannot be modified.
Lineweight Displays the lineweight associated with the layer. Clicking the
lineweight name displays a drop-down list with the available lineweights.
Linetype Displays the linetype associated with the layer. Clicking the linetype
name displays a drop-down list with the loaded linetypes. Choose Other at
the bottom of the drop-down list to display the Select Linetype dialog box
(page 550).
Transparency Controls the visibility of all objects on the selected layer. When
transparency is applied to individual objects, the objects transparency property
overrides the transparency setting of the layer. Drag the slider to adjust the
transparency of objects on the layer.
Plot (Print) Indicates if the objects on layer should be plotted or not.
If you turn off plotting for a layer, the objects on that layer are still displayed.
Layers that are off or frozen are not plotted, regardless of the Plot setting.
Plot Style Displays the plot style associated with the layer. If you are working
with color-dependent plot styles (the PSTYLEPOLICY (page 1410) system variable
is set to 1), you cannot change the plot style associated with a layer. Clicking
the plot style name displays a drop-down list with the available plot styles.
New VP Freeze Freezes the layer in new viewports created on a named (paper
space) layout.
For example, freezing the DIMENSIONS layer in all new viewports restricts
the display of dimensions on that layer in any newly created named layout
viewports but does not affect the DIMENSIONS layer in existing viewports. If
you later create a viewport that requires dimensions, you can override the
default setting by changing the current viewport setting.
VP Freeze (not available on the Model layout) Freezes the layer in the current
named (paper space) layout viewport. You can freeze or thaw layers in the
current viewport without affecting layer visibility in other viewports.
VP Freeze overrides the Thaw setting for a layer in the drawing. That is, you
can freeze a layer in the current viewport if it's thawed in the drawing, but
you can't thaw a layer in the current viewport if it's frozen or off in the
drawing. A layer is not visible when it is set to Off or Frozen in the drawing.
Commands | 541
VP Color (not available on the Model layout) Sets an override for the color
associated with the selected layer for the active named (paper space) layout
viewport.
VP Lineweight (not available on the Model layout) Sets an override for the
lineweight associated with the selected layer for the active named (paper space)
layout viewport.

LEADER
Creates a line that connects annotation to a feature.
Summary
It is recommended that you use the workflow available through the MLEADER
(page 651) command to create leader objects.
List of Prompts
The following prompts are displayed.
Specify leader start point:
Specify next point:
A leader line segment is drawn and prompts for points and options are
displayed.
Commands | 567
Specify next point (page ?) or [Annotation (page ?)/Format
(page ?)/Undo (page ?)] <Annotation>: Specify a point, enter an
option, or press Enter
Point Specification
Draws a leader line segment to the point specified and continues to prompt
you for points and options.
Annotation
Inserts an annotation at the end of the leader line. The annotation can be
single or multiple lines of text, a feature control frame containing geometric
tolerances, or a block.
If you press Enter at the Annotation prompt without entering text first, the
following options are displayed:
Tolerance Creates a feature control frame containing geometric tolerances
using the Geometric Tolerance dialog box (see TOLERANCE (page 1057)).
You can create datum indicators and basic dimension notation in these dialog
boxes. After you specify the geometric tolerance, LEADER ends.
Copy Copies text, a multiline text object, a feature control frame with
geometric tolerances, or a block and connects the copy to the end of the leader
line. The copy is associated with the leader line, meaning that if the copied
object moves, the end of the leader line moves with it. The display of the hook
line depends on the object copied.
The value of the current text gap (see DIMSTYLE (page 314) or the DIMGAP
(page 1232) system variable) determines where the text and multiline text objects
are inserted. Blocks or feature control frames with geometric tolerances are
attached to the end of the leader line.
Block Inserts a block at the end of the leader line. The prompts are the same
as for INSERT (page 519). The block reference is inserted at an offset from the
end of the leader line and is associated to the leader line, meaning that if the
block moves, the end of the leader line moves with it. No hook line is
displayed.
568 | Chapter 2 Commands
None Ends the command without adding any annotation to the leader line.
Mtext Creates text using the In-Place Text Editor (page 675) when you specify
an insertion point and a second point for the text boundary.
Enter the characters for the text. Enclose format strings for prefixes and suffixes
in angle brackets (< >). Enclose format strings for alternate units in square
brackets ([ ]). For more information about adding a prefix or suffix, see Control
the Display of Dimension Units in the User's Guide.
The units settings and the current text style determine how the text is
displayed. The multiline text is vertically centered and horizontally aligned
according to the X axis direction of the last two vertices of the leader line.
The text is offset from the hook line by the distance specified under Offset
from Dim Line on the Text tab of the New, Modify, or Override Dimension
Style dialog box (page 318). If the offset specified is negative, the multiline text
is enclosed in a box as a basic dimension.
Format
Controls the way the leader is drawn and whether it has an arrowhead.
Spline Draws the leader line as a spline. The vertices of the leader line are the
control points, each of equal unit weight.
Straight Draws the leader line as a set of straight line segments.
Arrow Draws an arrowhead at the start point of the leader line.
None Draws a leader line with no arrowhead at the start point.

Summary
Creates a 3D solid or surface by specifying a series of cross sections. The cross
sections define the shape of the resulting solid or surface. You must specify
at least two cross sections.
Loft cross sections can be open or closed, planar or non-planar, and can also
be edge subobjects. Open cross sections create surfaces and closed cross sections
create solids or surfaces, depending on the specified mode.

Refer to the Help system for a complete list of definitions for each of the region
or mass properties computed.
List of Prompts
The following prompts are displayed.
Select objects: Use an object selection method
If you select multiple regions, only those that are coplanar with the first
selected region are accepted.
MASSPROP displays the mass properties in the text window, and then asks if
you want to write the mass properties to a text file (.mpr).
The properties that MASSPROP displays depend on whether the selected objects
are regions, and whether the selected regions are coplanar with the XY plane
of the current user coordinate system (UCS), or 3D solids. For a list of the
parameters that control the MASSPROP units, see Calculations Based on the
Current UCS (page ?).

Commands | 611
Length of Segment Places point objects at the specified interval along the
selected object, starting at the endpoint closest to the point you used to select
the object.
Measurement of closed polylines starts at their initial vertex (the first one
drawn).
Measurement of circles starts at the angle from the center set as the current
snap rotation angle. If the snap rotation angle is 0, then the measurement of
the circle starts to the right of center, on its circumference.
The illustration shows how MEASURE marks 0.5-unit distances along a
polyline, with the PDMODE (page 1388) system variable set to 35.
Block Places blocks at a specified interval along the selected object.
Align Block With Object
Yes. The block is rotated about its insertion point so that its horizontal
lines are aligned with, and drawn tangent to, the object being measured.
No. The block is always inserted with a 0 rotation angle.
After you specify the segment length, the block is inserted at the specified
interval. If the block has variable attributes, these attributes are not included.

632 | Chapter 2 Commands
Summary
When you extrude, or extend, a mesh face, you can specify several options to
determine the shape of the extrusion. You can also determine whether
extruding multiple mesh faces results in joined or separate extrusions.
List of Prompts
The following prompts are displayed.
Mesh face(s) to extrude Specifies the mesh faces to extrude. Click one or
more faces to select them.
Height of extrusion (page 634)
Direction (page 634)
Path (page 634)
Taper angle (page 634)
Setting (Available only when you start the command before selecting faces)
Sets the style for extruding multiple adjacent mesh faces.
Join adjacent mesh faces when extruding Specifies whether adjacent
mesh faces are extruded singly or as a unit. (The difference between the
two options is not always apparent on a mesh that has not been smoothed.)
Yes. Extrudes all adjacent faces as a unit.
No. Extrudes each adjacent face separately.
Commands | 633
Height of extrusion Extrudes mesh faces along the Z axis. Enter a positive
value to extrude the face along the positive Z axis. Enter a negative value to
extrude along the negative Z axis. Multiple mesh faces do not need to be
parallel to the same plane.
Direction Specifies the length and direction of the extrusion. (The direction
cannot be parallel to the plane of the sweep curve created by the extrusion.)
Start point of direction. Specifies the first point in the direction vector.
End point of direction. Specifies the second point in the direction
vector.
Path Specifies an object, such as a line or spline, that determines the path and
length of the extrusion. The outline of the mesh face is swept along the path.
The new orientation of the swept mesh face is perpendicular to the endpoint
of the path.
The path should not lie on the same plane as the mesh face or have areas of
high curvature. For extrusions that adhere closely to the curved path, use a
spline, not an arced polyline, as the path.
Taper angle Sets an angle of taper for an extrusion.
634 | Chapter 2 Commands
Positive angles taper inward from the base mesh face. Negative angles taper
outward. The default angle, 0, extrudes the face perpendicular to the plane of
the mesh.
If the adjacent faces are not set to be joined, the faces that are selected for
extrusion are tapered to the same value. However, for joined extrusions, the
taper is applied only to the portion of the extrusion that is not adjacent to
another extruded face.
Specifying a large taper angle or a long extrusion height can cause the object
or portions of the object to taper to a point before reaching the extrusion
height.
Angle of taper. Sets an angle between -90 and +90 degrees.
Specify two points. Sets the taper angle to be the distance between two
specified points.

to 0 (zero). This level of smoothness becomes the new baseline for the object.
That is, the smoothness level can no longer be decreased beyond that level.
Refining a subobject does not reset the smoothing level.
List of Prompts
The following prompts are displayed.
Mesh object or face subobjects to refine Specifies 3D mesh objects or mesh
faces to be refined. Press Ctrl+click to isolate a specific face.

MESHSMOOTH
Converts 3D objects such as polygon meshes, surfaces, and solids to mesh
objects.
Access Methods
Menu: Draw 3D Modeling Meshes Smooth Mesh
Summary
Take advantage of the detailed modeling capabilities of 3D mesh by converting
objects such as 3D solids and surfaces to mesh.
Use this method to convert 3D faces (3DFACE) and legacy polygonal and
polyface meshes (from AutoCAD 2009 and earlier). You can also convert 2D
objects such as regions and closed polylines.
Commands | 637
The level of smoothness upon conversion depends on the mesh type setting
(FACETERMESHTYPE (page 1291) system variable). If the mesh type is not set
to be optimized, the converted object is not smoothed.
To convert mesh objects to 3D surfaces or solids, use CONVTOSOLID (page
223) or CONVTOSURFACE (page 225) commands.
Objects That Can Be Converted to Mesh
Object type
3D solids
3D surfaces
3D faces
Polyface and polygon meshes (legacy)
Regions
Closed polylines

MESHSMOOTHLESS
Decreases the level of smoothness for mesh objects by one level.
Access Methods
Menu: Modify Mesh Editing Smooth Less
Summary
Decrease the smoothness of selected mesh objects by one level. You can only
decrease the smoothness of objects whose level of smoothness is 1 or higher.
You cannot decrease the smoothness level of objects that have been refined.
638 | Chapter 2 Commands
You can decrease the smoothness of multiple objects. If the selected objects
have different levels of smoothness, their respective levels are decreased by
one. If the selection set contains ineligible objects, those objects can be filtered
out.

MESHSMOOTHMORE
Increases the level of smoothness for mesh objects by one level.
Access Methods
Menu: Modify Mesh Editing Smooth More
Summary
Smoothing increases the number of facets in the mesh, resulting in a rounder
object.
Commands | 639
Facets are the underlying components of each mesh face. You can increase
the smoothness level up to the value of SMOOTHMESHMAXLEV (page 1439)
as long as the number of faces does not exceed the value in the
SMOOTHMESHMAXFACE (page 1438) system variable. If you select multiple
objects with differing levels of smoothness, their respective levels are increased
by one.
You can only smooth mesh objects. However, you have the option of
converting some types of objects to mesh during the smoothing operation.
You can also filter out ineligible objects that you do not want to convert. For
a list of objects that can be converted, see MESHSMOOTH (page 637).

Because you specify the start and endpoint of the split, this method provides
greater control over the location of the split.
Commands | 641
For more precision in the placement of the split, you can specify that the split
starts or ends at a vertex. The Vertex option is useful for creating two triangular
faces from a rectangular face. It provides the precision you need if you later
want to spin the new edge using MESHSPIN (page 640).
List of Prompts
The following prompts are displayed:
Face to split In the drawing area, specifies which mesh face to split.
First split point on face edge. Sets the location on an edge of the mesh
face to start the split.

Summary
On the Model layout, you can create drawings in model space. The Model
layout automatically sets the TILEMODE (page 1464) system variable to 1, and
you can create model viewports to display various views of your drawing.
Once you have completed your drawing, you can choose a named (paper
space) layout to begin designing a layout environment from which to plot.
For possible performance gains when you switch between layouts or between
the Model and named layouts, use the LAYOUTREGENCTL (page 1350) system
variable to control how the display list is updated.

Stack Creates stacked text, for example, fractions, if the selected text contains
stack characters. Also, unstacks text if stacked text is selected. When the stack
characters, carat (^), forward slash (/), and pound sign (#), are used, the text
to the left of the stack character is stacked on top of the text to the right.
By default, text that contains a carat converts to left-justified tolerance values.
Text that contains the forward slash converts to center-justified fractional
numbers; the slash is converted to a horizontal bar the length of the longer
text string. Text that contains the pound sign converts to a fraction separated
by a diagonal bar the height of the two text strings. The characters above the
diagonal fraction bar are bottom-right aligned; the characters beneath the
diagonal bar are top-left aligned.

Line Spacing
Specifies line spacing for the multiline text object. Line spacing is the vertical
distance between the bottom (or baseline) of one line of text and the bottom
of the next line of text.
NOTE
Exact spacing is recommended when you use MTEXT to create a table. Use a
smaller text height than the specified line spacing to ensure that text does
not overlap.
At Least Adjusts lines of text automatically based on the height of the largest
character in the line. When At Least is selected, lines of text with taller
characters have added space between lines.
Distance Sets the line spacing to an absolute value measured in drawing units.
Valid values must be between 0.0833 (0.25x) and 1.3333 (4x).
694 | Chapter 2 Commands
Exactly Forces the line spacing to be the same for all lines of text in the
multiline text object. Spacing is based on the text height of the object or text
style.
Spacing Factor Sets the line spacing to a multiple of single-line spacing.
Single spacing is 1.66 times the height of the text characters. You can enter a
spacing factor as a number followed by x to indicate a multiple of single
spacing. For example, specify single spacing by entering 1x, or specify double
spacing by entering 2x.
Rotation
Specifies the rotation angle of the text boundary.
Specify rotation angle.
If you use the pointing device to specify a point, the rotation angle is
determined by the angle between the X axis and the line defined by the most
recently entered point (default 0,0,0) and the specified point.
The previous prompt is redisplayed until you specify the opposite corner of
the text boundary.
Style
Specifies the text style to use for multiline text.
Style Name Specifies a text style name. Text styles can be defined and saved
using the STYLE (page 1006) command.
?List Styles Lists text style names and characteristics.
The previous prompt is redisplayed until you specify the opposite corner of
the text boundary.
Width
Specifies the width of the text boundary.
If you use the pointing device to specify a point, the width is calculated as
the distance between the start point and the specified point. Words within
each line of the multiline text object wrap to fit the width of the text boundary.
If you specify a width of 0, word wrap is turned off and the width of the
multiline text object is as wide as the longest line of text. You can end a line
of text at a specific point by typing the text and pressing Enter. To end the
command, press Enter at the MTEXT prompt.
Columns
Specifies the column options for an mtext object.
Static Specifies the total column width, the number of columns, the gutter
width (the space between the columns), and the height of columns.

PEDIT
Edits polylines and 3D polygon meshes.
Access Methods
Menu: Modify Object Polyline
Shortcut menu: Select a polyline to edit. Right-click in the drawing area
and click Polyline Edit.
Summary
Common uses for PEDIT include joining 2D polylines, converting lines and
arcs into 2D polylines, and converting polylines into curves that approximate
B-splines (spline-fit polylines).
Commands | 767
List of Prompts
The following prompts are displayed.
Select polyline or [MULTIPLE (page 699)]: Use an object selection
method or enter m
The remaining prompts depend on whether you have selected a 2D polyline
(page 769), a 3D polyline (page 776), or 3D polygon mesh (page 779).
If the selected object is a line, arc, or a spline, the following prompt is
displayed:
Object selected is not a polyline.
Do you want it to turn into one? <Y>: Enter y or n, or press Enter
If you enter y, the object is converted into a single-segment 2D polyline that
you can edit. You can use this operation to join lines and arcs into a polyline.
Before the selected spline is converted to a polyline, the following prompt is
displayed:
Specify a precision <10>: Enter a new precision value or press Enter
The precision value determines how accurately the resulting polyline is to fit
to the source spline. Valid value is an integer between 0 and 99.
NOTE A high precision value may cause performance problems.
The PLINECONVERTMODE (page 1395) system variable determines whether
the polylines are created with linear or arc segments. When the PEDITACCEPT
(page 1389)system variable is set to 1, this prompt is suppressed, and the selected
object is automatically converted to a polyline.
The conversion in both PEDIT and SPLINEDIT will obey the DELOBJ (page
1213) system variable.

The entered precision value affects all splines in the selection set. The precision
value is an integer between 0 and 99.
2D Polyline Selection (PEDIT)
If you select a 2D polyline, the following prompt is displayed:
List of Prompts
The following prompts are displayed.
Enter an option [Close/Join/Width/Edit
vertex/Fit/Spline/Decurve/Ltype gen/Reverse/Undo]: Enter an option
or press Enter to end the command
NOTE
You can select a single arc or line segment, also called a subobject, within a
polyline by pressing the Ctrl key when you click over it.
If the polyline you select is a closed polyline, Open replaces the Close option
in the prompt. You can edit a 2D polyline if its normal is parallel to and in
the same direction as the Z axis of the current UCS.
Close
Creates the closing segment of the polyline, connecting the last segment with
the first. The polyline is considered open unless you close it using the Close
option.
Commands | 769
Open
Removes the closing segment of the polyline. The polyline is considered closed
unless you open it using the Open option.
Join
Adds lines, arcs, or polylines to the end of an open polyline and removes the
curve fitting from a curve-fit polyline. For objects to join the polyline, their
endpoints must touch unless you use the Multiple option at the first PEDIT
prompt. In this case, you can join polylines that do not touch if the fuzz
distance is set to a value large enough to include the endpoints.
Jointype
Sets the method of joining selected polylines.
Extend Joins the selected polylines by extending or trimming the segments
to the nearest endpoints.
Add Joins the selected polylines by adding a straight segment between the
nearest endpoints.
Both Joins the selected polylines by extending or trimming if possible.
Otherwise joins the selected polylines by adding a straight segment between
the nearest endpoints.
Width
Specifies a new uniform width for the entire polyline.
You can use the Width option of the Edit Vertex option to change the starting
and ending widths of a segment.
Edit Vertex
Marks the first vertex of the polyline by drawing an X on the screen. If you
have specified a tangent direction for this vertex, an arrow is also drawn in
that direction.
770 | Chapter 2 Commands
Next
Moves the X marker to the next vertex. The marker does not wrap around
from the end to the start of the polyline even if the polyline is closed.
Previous
Moves the X marker to the previous vertex. The marker does not wrap around
from the start to the end of the polyline even if the polyline is closed.
Break
Saves the location of the marked vertex while you move the X marker to any
other vertex.
If one of the specified vertices is at an end of the polyline, the result is one
truncated polyline. If both specified vertices are at endpoints of the polyline,
or if just one vertex is specified and it is at an endpoint, you cannot use Break.
Next (page ?)
Previous (page ?)
Go Deletes any segments and vertices between the two vertices you specify
and returns to Edit Vertex mode.
Exit Exits Break and returns to Edit Vertex mode.
Insert
Adds a new vertex to the polyline after the marked vertex.
Commands | 771
Move
Moves the marked vertex.
Regen
Regenerates the polyline.
Straighten
Saves the location of the marked vertex while you move the X marker to any
other vertex.
If you want to remove an arc segment that connects two straight segments of
a polyline and then extend the straight segments until they intersect, use the
FILLET (page 432) command with a fillet radius of 0.
Next Moves the X marker to the next vertex.
Previous Moves the X marker to the previous vertex.
Go Deletes any segments and vertices between the two vertices you select,
replaces them with single straight line segments, and returns to Edit Vertex
mode. If you specify only one vertex by entering go without moving the X
marker, the segment following that vertex is straightened if it is an arc.
Exit Exits Straighten and returns to Edit Vertex mode.
772 | Chapter 2 Commands
Tangent
Attaches a tangent direction to the marked vertex for use later in curve fitting.
Width
Changes the starting and ending widths for the segment that immediately
follows the marked vertex.
You must regenerate the polyline to display the new width.
Exit
Exits Edit Vertex mode.
Fit
Creates an arc-fit polyline, a smooth curve consisting of arcs joining each pair
of vertices. The curve passes through all vertices of the polyline and uses any
tangent direction you specify.
Spline
Uses the vertices of the selected polyline as the control points, or frame, of a
curve approximating a B-spline. This curve, called a spline-fit polyline, passes
through the first and last control points unless the original polyline was closed.
The curve is pulled toward the other points but does not necessarily pass
through them. The more control points you specify in a particular part of the
frame, the more pull they exert on the curve. Quadratic and cubic spline-fit
polylines can be generated.
Commands | 773
Spline-fit polylines are very different from the curves produced by the Fit
option. Fit constructs pairs of arcs that pass through every control point. Both
of these curves are different from true B-splines produced with the SPLINE
(page 988) command.
If the original polyline included arc segments, they are straightened when the
spline's frame is formed. If the frame has width, the resulting spline tapers
smoothly from the width of the first vertex to the width of the last vertex. All
intermediate width information is ignored. Once spline-fit, the frame, if
displayed, is shown with zero width and CONTINUOUS linetype. Tangent
specifications on control point vertices have no effect on spline-fitting.
When a spline-fit curve is fit to a polyline, the spline-fit curve's frame is stored
so that it can be recalled by a subsequent decurving. You can turn a spline-fit
curve back into its frame polyline by using the PEDIT Decurve option. This
option works on fit curves in the same manner as it does on splines.
Most editing commands act the same when applied to spline-fit polylines or
fit curves.
MOVE (page 671), ERASE (page 406), COPY (page 228), MIRROR (page 647),
ROTATE (page 907), and SCALE (page 916) operate on both the spline curve
and its frame, whether the frame is visible or not.
EXTEND (page 410) changes the frame by adding a new vertex where the
initial or final line of the frame intersects the boundary geometry.
BREAK (page 155) and TRIM (page 1067) generate a polyline with only the fit
spline, which is consistent with fit curves, where the curve fitting is
permanent.
EXPLODE (page 407) deletes the frame and generates lines and arcs to
approximate the spline-fit polyline.
OFFSET (page 715) generates a polyline with only the fit spline, which is
consistent with its behavior with fit curves.
DIVIDE (page 356), MEASURE (page 611), and the Object option of AREA
(page 83) and HATCH (page 471) see only the fit spline, not the frame.
STRETCH (page 1004) refits the spline to the stretched frame after a spline
is stretched.
774 | Chapter 2 Commands
The Join option of PEDIT decurves the spline and discards the spline
information of the original and any added polylines. Once the Join operation
is complete, you can fit a new spline to the resulting polyline.
The Edit Vertex options of PEDIT have the following effect:
The Next and Previous options move the X marker only to points on the
frame of the spline, whether visible or not.
The Break option discards the spline.
The Insert, Move, Straighten, and Width options automatically refit the
spline.
The Tangent option has no effect on splines.
Object snap uses only the spline-fit curve itself, not the frame. If you want to
snap to the frame control points, use PEDIT to recall the polyline frame first.
The SPLINETYPE (page 1446) system variable controls the type of spline curve
approximated. Setting SPLINETYPE to 5 approximates a quadratic B-spline.
Setting SPLINETYPE to 6 approximates a cubic B-spline.
You can examine or change the fineness or coarseness of the spline
approximation with the SPLINESEGS (page 1446) system variable, or you can
use AutoLISP®. The default value is 8. If you set the value higher, a greater
number of line segments are drawn and the approximation to the ideal spline
becomes more precise. The generated spline occupies more space in the drawing
file and takes longer to generate.
If you set SPLINESEGS to a negative value, the program generates segments
using the absolute value of the setting and then applies a fit-type curve to
those segments. Fit-type curves use arcs as the approximating segments. Using
arcs yields a smoother generated curve when few segments are specified, but
the curve can take longer to generate.
Commands | 775
To change the number of segments used to fit an existing spline, change
SPLINESEGS and respline the curve. You do not have to decurve it first.
Decurve
Removes extra vertices inserted by a fit or spline curve and straightens all
segments of the polyline. Retains tangent information assigned to the polyline
vertices for use in subsequent fit curve requests. If you edit a spline-fit polyline
with a command such as BREAK (page 155) or TRIM (page 1067), you cannot use
the Decurve option.
Ltype Gen
Generates the linetype in a continuous pattern through the vertices of the
polyline. When turned off, this option generates the linetype starting and
ending with a dash at each vertex. Ltype Gen does not apply to polylines with
tapered segments.
Reverse
Reverses the order of vertices of the polyline. Use this option to reverse the
direction of objects that use linetypes with included text. For example,
depending on the direction in which a polyline was created, the text in the
linetype might be displayed upside down.
Undo
Reverses operations as far back as the beginning of the PEDIT session.
3D Polyline Selection (PEDIT)
If you select a 3D polyline, the following prompt is displayed:

mode. If you specify only one vertex by entering go without moving the X
marker, the segment following that vertex is made straight if it is an arc.
Exit Exits Straighten and returns to Edit Vertex mode.
To remove an arc segment that connects two straight segments of a polyline
and then to extend the straight segments until they intersect, use the FILLET
(page 432) command with a fillet radius of 0.
Exit
Exits Edit Vertex mode.
Spline Curve
Fits a 3D B-spline curve to its control points. The SPLFRAME (page 1445) system
variable controls the accuracy and display of the control points for the 3D
B-spline, whose curves can be approximated only by line segments. Negative
values for spline segments are ignored.
Decurve
Removes extra vertices inserted by a fit or spline curve and straightens all
segments of the polyline. Retains tangent information assigned to the polyline
vertices for use in subsequent fit curve requests. If you edit a spline-fit polyline
with a command such as BREAK (page 155) or TRIM (page 1067), you cannot use
the Decurve option.
Reverse
Reverses the order of vertices of the polyline. Use this option to reverse the
direction of objects that use linetypes with included text. For example,
778 | Chapter 2 Commands
depending on the direction in which a polyline was created, the text in the
linetype might be displayed upside down.
Undo

PFACE
Creates a 3D polyface mesh vertex by vertex.
List of Prompts
The following prompts are displayed.
Specify location for vertex (page ?) 1: Specify a point
Specify location for vertex 2 or <define faces (page ?)>:
Specify a point or press Enter
Specify location for vertex nor <define faces>: Specify a point
or press Enter
Vertex Location
You specify all vertices used in the mesh. The vertex numbers displayed in
the prompts are the numbers used to reference each vertex. The prompt is
repeated until you press Enter. If you press Enter on a blank line, you are
prompted for the vertices to be assigned to each face.
Define Faces
Vertex Number You define each face by entering vertex numbers for all the
vertices of that face. The mesh is drawn after you have defined the last face
and pressed Enter after the prompt.
Commands | 781
To make an edge invisible, you can enter a negative vertex number for the
beginning vertex of the edge.
You can create polygons with any number of edges. PFACE automatically
breaks them into multiple face objects with the appropriate invisible edges.
Faces with one or two vertices behave like point or line objects without the
special properties of Point Display modes or linetypes. You can use them to
embed wireframe images within a mesh. Use Endpoint object snap to snap to
a face composed of one or two vertices. All object snap modes that apply to
line objects work with visible edges of polyface meshes. You cannot use PEDIT
(page 767) to edit polyface meshes.
Color Faces created with PFACE adopt the current layer and color. Unlike
polyline vertices, polyface mesh faces can be created with layer and color
properties different from their parent object.
You can enter a color from the AutoCAD Color Index (a color name or
number), a true color, or a color from a color book.
Layer Faces created with PFACE adopt the current layer and color. Unlike
polyline vertices, polyface mesh faces can be created with layer and color
properties different from their parent object. Layer visibility behaves normally
on faces of a polyface mesh. However, if you create a polyface mesh on a
frozen layer, the program does not generate any of its faces, including those
on non-frozen layers.

Summary
A 2D polyline is a connected sequence of segments created as a single planar
object. You can create straight line segments, arc segments, or a combination
of the two.
NOTE
A temporary plus-shaped marker displays at the first point. This marker can
be useful when you create long and complicated polylines. It is removed when
you complete the polyline.
The PLINEGEN (page 1396) system variable controls the linetype pattern display
around and the smoothness of the vertices of a 2D polyline. Setting PLINEGEN
to 1 generates new polylines in a continuous pattern around the vertices of
the completed polyline. Setting PLINEGEN to 0 starts and ends the polyline
with a dash at each vertex. PLINEGEN does not apply to polylines with tapered
segments.

Summary
Lists all of the plot styles in the plot style table and their settings.
Plot styles are displayed in columns from left to right. The first plot style in a
named plot style table is NORMAL and represents an object's default properties
(no plot style applied). You cannot modify or delete the NORMAL style.
810 | Chapter 2 Commands
List of Options
The following options are displayed.
Plot Styles
Displays the names of plot styles in named plot style tables. Plot styles in
named plot style tables can be changed. Plot style names in color-dependent
plot style tables are tied to object color and cannot be changed. The program
accepts up to 255 characters for style names.
Add Style (+)
Adds a new plot style to a named plot style table.
The plot style is based on Normal, which uses an object's properties and doesn't
apply any overrides by default. You must specify the overrides you want to
apply after you create the new plot style. You cannot add a new plot style to
a color-dependent plot style table; a color-dependent plot style table has 255
plot styles mapped to color. You also cannot add a plot style to a named plot
style table that has a translation table.
Delete Style (-)
Deletes the selected style from a named plot style table.
Objects assigned this plot style retain the plot style assignment but plot as
Normal because the plot style is no longer defined in the plot style table. You
cannot delete a plot style from a named plot style table that has a translation
table, or from a color-dependent plot style table.
Color
Specifies the plotted color for an object. The default setting for plot style color
is Use Object Color. If you assign a plot style color, the color overrides the
object's color at plot time.
You can choose Select Color to display the Color Palette dialog box (page 198)
and select one of the 255 AutoCAD Color Index (ACI) colors, a true color, or
a color from a color book. The color you specify is displayed in the plot style
color list as Custom Color. If the plot device does not support the color you
specify, it plots the nearest available color or, in the case of monochrome
devices, black.
Dithering
Enables dithering. A plotter uses dithering to approximate colors with dot
patterns, giving the impression of plotting more colors than available in the
AutoCAD Color Index (ACI). If the plotter does not support dithering, the
dithering setting is ignored.
Dithering is usually turned off in order to avoid false line typing that results
from dithering of thin vectors. Turning off dithering also makes dim colors
Commands | 811
more visible. When you turn off dithering, the program maps colors to the
nearest color, resulting in a smaller range of colors when plotting.
Grayscale
Converts the object's colors to grayscale if the plotter supports grayscale. If
you clear Convert to Grayscale, the RGB values are used for object colors.
Dithering is available whether you use the object's color or assign a plot style
color.
Screening
Specifies a color intensity setting that determines the amount of ink placed
on the paper while plotting. Selecting 0 reduces the color to white. Selecting
100 displays the color at its full intensity. The Dithering option must be
selected for screening.
Linetype
Displays a list with a sample and a description of each linetype. If you assign
a plot style linetype, the linetype overrides the object's linetype at plot time.
Adaptive
Adjusts the scale of the linetype to complete the linetype pattern.
If you do not select Adaptive, the line might end in the middle of a pattern.
Turn off Adaptive if linetype scale is important. Turn on Adaptive if complete
linetype patterns are more important than correct linetype scaling.
Lineweight
Displays a sample of the lineweight as well as its numeric value. You can
specify the numeric value of each lineweight in millimeters.
If you assign a plot style lineweight, the lineweight overrides the object's
lineweight when it is plotted.
Edit Lineweights Modifies the widths values of existing lineweights.
Displays the Edit Lineweights dialog box.
There are 28 lineweights available to apply to plot styles in plot style tables.
If the lineweight you need does not exist in the list of lineweights stored in
the plot style table, you can edit an existing lineweight. You cannot add or
delete lineweights from the list in the plot style table.
Line End Style
If you assign a line end style, the line end style overrides the object's line end
style at plot time.
Line Join Style
If you assign a line join style, the line join style overrides the object's line join
style at plot time.
812 | Chapter 2 Commands
Fill Style
If you assign a fill style, the fill style overrides the object's fill style at plot
time.
Pen#
Specifies a pen to use when plotting objects that use this plot style. Available
pens range from 1 to 32. If plot style color is set to Use Object Color, or you
are editing a plot style in a color-dependent plot style table, the value is set
to Automatic.
If you specify 0, the field updates to read Automatic. The program determines
the pen of the closest color to the object you are plotting using the information
specified as part of the plotter.
Virtual Pen#
Specifies a virtual pen number between 1 and 255. Many non-pen plotters
can simulate pen plotters using virtual pens. For many devices, you can
program the pen's width, fill pattern, end style, join style, and color/screening
from the front panel on the plotter.
Enter 0 or Automatic to specify that the program should make the virtual pen
assignment from the AutoCAD Color Index.
The virtual pen setting in a plot style is used only by non-pen plotters and
only if they are configured for virtual pens. If this is the case, all the other
style settings are ignored and only the virtual pen is used. If a non-pen plotter
is not configured for virtual pens, then the virtual and physical pen
information in the plot style is ignored and all the other settings are used.
Description
Provides a description for each plot style.

Access Methods
Button
Toolbar: Drafting tool set Open Shapes tool group (expanded)
Point flyout Multiple Points
Menu: Draw Point Single
Summary
Points can act as nodes to which you can snap objects. You can specify a full
three-dimensional location for a point. The current elevation is assumed if
you omit the Z coordinate value.
The PDMODE (page 1388) and PDSIZE (page 1389) system variables control the
appearance of point objects. PDMODE values 0, 2, 3, and 4 specify a figure to
draw through the point. A value of 1 specifies that nothing is displayed.
Specifying the value 32, 64, or 96 selects a shape to draw around the point,
in addition to the figure drawn through it:
Commands | 815
PDSIZE controls the size of the point figures, except for PDMODE values 0
and 1. A setting of 0 generates the point at 5 percent of the drawing area
height. A positive PDSIZE value specifies an absolute size for the point figures.
A negative value is interpreted as a percentage of the viewport size.
After you change PDMODE and PDSIZE, the appearance of existing points
changes the next time the drawing is regenerated.
You can use MEASURE and DIVIDE to create points along an object. Use
DDPTYPE to specify point size and styles easily.

Commands | 819
Attenuation Type Controls how light diminishes over distance. The farther
away an object is from a point light, the darker the object appears. Attenuation
is also known as decay.
Enter attenuation type [None/Inverse linear/inverse Squared] <Inverse linear>:
None. Sets no attenuation. Objects far from the point light are as bright
as objects close to the light.
Inverse Linear. Sets attenuation to be the inverse of the linear distance
from the light. For example, at a distance of 2 units, light is half as strong
as at the point light; at a distance of 4 units, light is one quarter as strong.
The default value for inverse linear is half the maximum intensity.
Inverse Squared. Sets attenuation to be the inverse of the square of the
distance from the light. For example, at a distance of 2 units, light is one
quarter as strong as at the point light; at a distance of 4 units, light is one
sixteenth as strong.
Use Limits Specifies whether to use limits or not.
Limits [oN/oFf] <Off>:
Attenuation Start Limit Specifies the point where light starts as an offset
from the center of the light. The default is 0.
Specify start limit offset <1.0000>:
Attenuation End Limit Specifies the point where light ends as an offset from
the center of the light. No light is cast beyond this point. Setting an end limit
increases performance where the effect of lighting is so minimal that the
calculations are wasted processing time.
Specify end limit offset <10.0000>:

Properties Inspector palette (page 832) is displayed.
List of Options
The following options are displayed.
Commands | 837
General Properties
The following property settings are available:
Name Specifies the name of the light.
Type (Light Distribution) Specifies the type of light. Determines the
distribution of light from the . The type of lighting can be changed after the
light has been added to the drawings.
Spotlight - Default value for Spotlight and Freespot lights.
Point - Default for Pointlight and Targetpoint lights.
Web - Default for Weblight and Freeweb lights.
On/Off Status Indicates whether the light is on or off.
Shadows Indicates if the light is casting a shadow.
Hotspot Angle (Spotlight and Freespot only) Specifies the angle of the
brightest cone of light.
Falloff Angle (Spotlight and Freespot only) Specifies the outer extremity of
the light, where it meets the darkness.
Intensity Factor Magnifies the effect of the skylight.
Filter Color Specifies the secondary color of the light. Represents the color of
a physical filter over the lamp. Default color is white.
When lighting is set to photometric units this represents a secondary color
filter on the light. When lighting is set to generic lighting this represents the
total color of the light.
Plot Glyph Allows the ability to plot the drawing with the glyphs on.
Photometric Properties
The following property settings are available:
Lamp Color Specifies the inherent color of the light in Kelvin temperature
or standard.
Resulting Color Reports the final color of the light. This is determined by a
combination of the Lamp Color and the Filter Color. (Read-only)
Intensity Method Specifies the value in which light intensity should be
measured.
Intensity (Candela). Specifies the number of candelas (cd) is the SI unit
of luminous intensity (perceived power emitted by a light source in a
particular direction).
838 | Chapter 2 Commands
Flux (Lumen). Represents the rate of total energy leaving the lamp. It is
specified in lumens (SI and American). Mathematically, the flux is the
integral of the luminous intensity over the sphere. The calculation of flux
depends on the distribution of intensities. For a point light with constant
intensity, the flux is simply the product of the intensity and the solid angle
of a sphere: 4 Pi * Intensity. For a spot light, the flux is the product of the
intensity and the solid angle of the hotspot cone, plus the incremental
solid angle of the fall-off region. For a weblight, there isnt any analytical
formula. The flux is obtained by numerically integrating the intensities
provided in the web file.
Illuminance (Foot-candles). Represents the energy per area arriving at
a surface (Area-flux-density). It is specified in lux (SI) and foot-candles
(American). For a near light, because the light rays are diverging, you have
to talk about the illuminance at a specific distance from the lamp. So this
requires an extra control to specify this distance and an additional
affordance in the viewport to show the distance.
Lamp Intensity Specifies the brightness of a lamp. More specifically, it
represents the luminous intensity, or power in a particular direction.
Intensity Factor Magnifies the effect of the skylight.
Resulting Intensity Reports the final brightness of the light. This is determined
by the product of the Lamp Intensity and the Intensity factor. (Read-only)
PhotometricWeb
The following property settings are available for Web and Freeweb lights:
Web File Specifies the data file describing the intensity distribution of the
light.
Web Offsets
Under the Web offsets panel, the following property settings are available
under the Weblight and Freeweb types of lights:
Rotate X Specifies a rotational offset of the web about the optical X axis.
Rotate Y Specifies a rotational offset of the web about the optical Y axis.
Rotate Z Specifies a rotational offset of the web about the optical Z axis.
Geometry
Under the Geometry panel, the following property settings are available:
Position X Specifies the X coordinate position of the light.
Position Y Specifies the Y coordinate position of the light.
Commands | 839
Position Z Specifies the Z coordinate position of the light.
Target X Specifies the X coordinate target position of the light. (Spotlight,
Targetpoint, and Weblight only)
Target Y Specifies the Y coordinate target position of the light. (Spotlight,
Targetpoint, and Weblight only)
Target Z Specifies the Z coordinate target position of the light. (Spotlight,
Targetpoint, and Weblight only)
Targeted Specifies if the light displays a target grip for orienting the light.
Disabled is the default for Freespot, Pointlight, and Freeweb. Enabled is the
default for Spotlight, Targetpoint, and Weblight.
Attenuation
In the real world, the intensity of light diminishes over distance. Objects far
from the light source appear darker than objects near the source. This effect
is known as attenuation. Attenuation is available under standard lighting
workflow only. Under the Attenuation panel the following property settings
are available:
Type Controls how light diminishes over distance. The farther away an object
is from a spotlight, the darker the object appears. Attenuation is also known
as decay.
Inverse Linear (Standard lights only). Sets attenuation to be the inverse of
the linear distance from the light. For example, at a distance of 2 units,
light is half as strong as at the point light; at a distance of 4 units, light is
one quarter as strong. The default value for inverse linear is half the
maximum intensity.
Inverse Square (Photometric lights). Sets attenuation to be the inverse of
the square of the distance from the light. For example, at a distance of 2
units, light is one quarter as strong as at the spotlight; at a distance of 4
units, light is one sixteenth as strong.
None (Standard lights only). Sets no attenuation. Objects far from the
point light are as bright as objects close to the light.
Use Limits Specifies whether to use limits. The default is No. (Standard lights
only)
Rendered Shadow Details
Under the Rendered Shadow Details panel, the following property settings
are available:
840 | Chapter 2 Commands
Type Specifies the type of shadow cast by the light.
Soft (shadow map). Sets the type to Soft. This selection activates additional
options for Map size and Softness.
Sharp (default). Sets the rendered shadow to sharp.
Soft (sampled). Sets attenuation to be the inverse of the square of the
distance from the light. For example, at a distance of 2 units, light is one
quarter as strong as at the spotlight; at a distance of 4 units, light is one
sixteenth as strong.
Map Size Specifies the size of the shadow map. (Soft shadow map type only)
Softness Specifies the softness or fuzziness of the shadow-mapped shadow.
(Soft shadow map type only)
Samples Specifies the number of shadow rays for the light. (Soft sampled type
only)

Copy an Object
Prompts you to copy a multiline text, single-line text, tolerance, or block
reference object and connects the copy to the end of the leader line. The copy
is associated with the leader line, meaning that if the copied object moves,
the end of the leader line moves with it. The display of the hook line depends
on the object copied.
Tolerance
Displays the Tolerance dialog box, which you can use to create a feature control
frame to attach to the leader.
Block Reference
Prompts you to insert a block reference. The block reference is inserted at an
offset from the end of the leader line and is associated to the leader line,
meaning that if the block moves, the end of the leader line moves with it. No
hook line is displayed.
None
Creates a leader with no annotation.
856 | Chapter 2 Commands
MText Options
The options are available only when the multiline text annotation type is
selected.

are uniquely altered.
If selected, named objects in xrefs are altered (names are prefixed with $#$),
similar to the way they are altered when you bind xrefs. If cleared, the names
of layers and other named objects remain the same as in the reference drawing.
Named objects that are not altered to make them unique assume the properties
of those in the current host drawing that share the same name.
Display Attribute Definitions for Editing
Controls whether all variable attribute definitions in block references are
extracted and displayed during reference editing.
If Display Attribute Definitions for Editing is selected, the attributes (except
constant attributes) are made invisible, and the attribute definitions are
available for editing along with the selected reference geometry. When changes
are saved back to the block reference, the attributes of the original reference
remain unchanged. The new or altered attribute definitions affect only
subsequent insertions of the block; the attributes in existing block instances
are not affected. Xrefs and block references without definitions are not affected
by this option.
874 | Chapter 2 Commands
Lock Objects Not in Working Set

The currently selected reference is highlighted.
Commands | 875
A working set is formed with the objects you have selected for editing. The
working set includes objects that can be saved back to update the xref or block
definition. When you save back changes, changes made to the objects in the
reference file are saved without actually opening the reference drawing or
recreating the block. The working set is visually distinct from the rest of the
current drawing: all objects in the current drawing, except objects in the
working set, appear faded. The XFADECTL (page 1526) system variable controls
the fading of objects while you edit a reference in place.
You can select objects in xrefs for editing even if they are on a locked layer in
the reference file. When a reference object is part of the working set, you can
unlock the object's layer and make changes to the object. Only the changes
made to the object are saved back to the reference file; the xref layer remains
locked in the reference file.
NOTE
Objects outside of the working set are not faded unless the visual style is set
to 2D Wireframe during in-place reference editing.

Converts an object that encloses an area into a region object.
Access Methods
Button
Toolbar: Drafting tool set Closed Shapes tool group (expanded)
Region
Menu: Draw Region
Summary
Regions are two-dimensional areas you create from closed shapes or loops.
Closed polylines, lines, and curves are valid selections. Curves include circular
arcs, circles, elliptical arcs, ellipses, and splines.
You can combine several regions into a single, complex region.
Closed 2D and exploded planar 3D polylines in the selection set are converted
to separate regions and then converts polylines, lines, and curves to form
Commands | 879
closed planar loops (outer boundaries and holes of a region). If more than two
curves share an endpoint, the resulting region might be arbitrary.
The boundary of the region consists of end-connected curves where each point
shares only two edges. All intersections and self-intersecting curves are rejected.
If a selected polyline has been smoothed by either the Spline or Fit option of
PEDIT (page 767), the resulting region contains the line or arc geometry of the
smoothed polyline. The polyline is not converted to a spline object.
REGION deletes the original objects after converting them to regions unless
the system variable DELOBJ (page 1213) is set to 0. If the original objects were
hatched, hatch associativity is lost. To restore associativity, rehatch the region.

bureau or import the image into a page-layout program.
Clicking Save after choosing this format displays the TIFF Image Options
dialog box (page 888).
JPEG (*.jpg) JPEG (.jpeg or .jpg) files follow the standards set by the Joint
Photography Experts Group. These files use a variable compression method
Commands | 885
that is called lossy compression because of the loss of image quality as you
increase the compression. However, the JPEG compression scheme is extremely
good and you can sometimes compress the file up to 200:1 without severe
loss of image quality. JPEG is consequently a popular format for posting image
files on the Internet for minimum file size and minimum download time.
Clicking Save after choosing this format displays the JPEG Image Options
dialog box (page 889).
PNG (*.png) PNG (Portable Network Graphics) is a still-image file format

-RENDER
Creates a photorealistic or realistically shaded image of a 3D solid or surface
model from the Command prompt.
List of Prompts
The following prompts are displayed.
890 | Chapter 2 Commands
Specify render preset [Draft (page ?)/Low (page ?)/Medium
(page ?)/High (page ?)/Presentation (page ?)/Other (page
?)] <Medium>: Enter an option or press Enter
Specify render destination [Render Window (page ?)/Viewport
(page ?)] <Render Window>: Enter an option or press Enter
Draft
Draft is the lowest level standard render preset. This setting
is intended for very fast, test renderings where anti-aliasing is bypassed and
sample filtering is very low.
This render preset produces very low quality rendering, but results in the
fastest rendering speed.
Low
The Low render preset provides better quality than the
Draft preset. Anti-aliasing is bypassed but sample filtering is improved.
Raytracing is also active, by default, so better quality shading occurs.
This preset is best used for test rendering that requires better quality than
Draft.
Medium
You can expect much better sample filtering and
anti-aliasing is active when you use the Medium render preset. Raytracing is
active with increased reflection depth settings when compared to the Low
render preset.
This preset offers a good balance between quality and render speed.
Commands | 891
High
The High we preset matches the Medium preset settings
with regards to anti-aliasing, but sample filtering and raytracing is improved.
Due to the improved sample filtering and raytracing, rendered images take
longer to process, but the image quality is much better.
Presentation
The Presentation render preset is used for high quality,
photo-realistic rendered images and takes the longest to process. Sample
filtering and raytracing is further improved.
Since this preset is used for final renderings, global illumination settings are
commonly used in conjunction.
Other
The Other option allows you to specify a custom render preset if one or more
are present.
?List Custom Render Presets Lists all the custom render presets that are
stored with the model. Only custom render presets are listed.
Render Window
The image will be displayed in the render window when processing in

information, see Understand the UCS in 3D.
List of Prompts
The following prompts are displayed.
Objects to Revolve Specifies the objects to be revolved about an axis.
Mode Controls whether the revolve action creates a solid or a surface. Surfaces
are extended as either NURBS surfaces or procedural surfaces, depending on
the SURFACEMODELINGMODE (page 1453) system variable.
Axis Start Point Specifies the first point of the axis of revolution. The positive
axis direction is from the first to the second point.
Axis Endpoint Sets the endpoint for the axis of revolution.
Start Angle Specifies an offset for the revolution from the plane of the object
being revolved.
Drag your cursor to specify and preview the start angle of the object.
Angle of Revolution Specifies how far the selected object revolves about the
axis.
A positive angle revolves the objects in a counterclockwise direction. A negative
angle revolves the objects in a clockwise direction. You can also drag the cursor
to specify and preview the angle of revolution.
Object Specifies an existing object to be used as an axis. The positive axis
direction is from the closest to the farthest endpoint of this object.
Commands | 903
You can use lines, linear polyline segments, and linear edges of solids or
surfaces as an axis.
NOTE
Select an edge subobject by pressing Ctrl while you select an edge.
X (Axis) Sets the positive X axis of the current UCS as the positive axis
direction.
Y (Axis) Sets the positive Y axis of the current UCS as the positive axis
direction.
Z (Axis) Sets the positive Z axis of the current UCS as the positive axis
direction.

REVSURF
Creates a mesh by revolving a profile about an axis.
Access Methods
Menu: Draw 3D Modeling Meshes Revolved Meshes
Summary
Select a line, arc, circle, or 2D or 3D polyline to sweep in a circular path around
a selected axis.
The MESHTYPE (page 1369) system variable sets which type of mesh is created.
Mesh objects are created by default. Set the variable to 0 to create legacy
polyface or polygon mesh.
Commands | 905
The density of the generated mesh is controlled by the SURFTAB1 (page 1454)
and SURFTAB2 (page 1454) system variables. SURFTAB1 specifies the number of
tabulation lines that are drawn in the direction of revolution. If the path curve
is a line, arc, circle, or spline-fit polyline, SURFTAB2 specifies the number of
tabulation lines that are drawn to divide it into equal-sized intervals. If the
path curve is a polyline that has not been spline fit, tabulation lines are drawn
at the ends of straight segments, and each arc segment is divided into the
number of intervals specified by SURFTAB2.
List of Prompts
The following prompts are displayed.
Current wire frame density: SURFTAB1=current SURFTAB2=current
Object to revolve Select a line, arc, circle, or 2D or 3D polyline.
Object that defines axis of revolution Select a line or open 2D or 3D polyline.
The axis direction cannot be parallel to the plane of the original object.
The path curve is swept about the selected axis to define the mesh. The path
curve defines the N direction of the mesh. Selecting a circle or a closed polyline
as the path curve closes the mesh in the N direction.
906 | Chapter 2 Commands
The vector from the first to the last vertex of the polyline determines the
rotation axis. Any intermediate vertices are ignored. The axis of revolution
determines the M direction of the mesh.
Start Angle If set to a nonzero value, starts the mesh of revolution at an offset
from the generating path curve.
Specifying a start angle starts the mesh of revolution at an offset from the
generating path curve.
Included Angle Specifies how far about the axis of revolution the mesh
extends. The included angle is the distance through which the path curve is
swept.
Entering an included angle that is less than a full circle prevents the circle
from closing.
The point you use to select the axis of revolution affects the direction of
revolution. The mesh in the following example was created by specifying a
start angle of 0 degrees and an included angle of 90 degrees.

RULESURF
Creates a mesh that represents the surface between two lines or curves.
Access Methods
Menu: Draw 3D Modeling Meshes Ruled Mesh
Summary
Select two edges that define the mesh. The edges can be lines, arcs, splines,
circles, or polylines. If one of the edges is closed, then the other edge must
also be closed. You can also use a point as one edge for either an open or a
closed curve.
The MESHTYPE (page 1369) system variable sets which type of mesh is created.
Mesh objects are created by default. Set the variable to 0 to create legacy
polyface or polygon mesh.
For closed curves, the selection does not matter. If the curve is a circle, the
ruled mesh begins at the 0-degree quadrant point, as determined by the current
X axis plus the current value of the SNAPANG (page 1439) system variable. For
closed polylines, the ruled mesh starts at the last vertex and proceeds backward
along the segments of the polyline. Creating a ruled mesh between a circle
912 | Chapter 2 Commands
and a closed polyline can be confusing. Substituting a closed semicircular
polyline for the circle might be preferable.
The ruled mesh is constructed as a 2 by N polygon mesh. RULESURF places
half the mesh vertices at equal intervals along one defining curve, and the
other half at equal intervals along the other curve. The number of intervals
is specified by the SURFTAB1 (page 1454) system variable. It is the same for each
curve; therefore, the distance between the vertices along the two curves differs
if the curves are of different lengths.
The N direction of the mesh is along the boundary curves. If both boundaries
are closed, or if one is closed and the other is a point, the resulting polygon
mesh is closed in the N direction and N equals SURFTAB1. If both boundaries
are open, N equals SURFTAB1 + 1, because division of a curve into n parts
requires n + 1 tabulations.
The 0,0 vertex of the mesh is the endpoint of the first selected curve nearest
the point you used to select that curve.
Selecting objects at the same ends creates a polygon mesh.
Selecting objects at opposite ends creates a self-intersecting polygon mesh.
List of Prompts
The following prompts are displayed.
Commands | 913
First defining curve Specifies an object and start point for the new mesh
object.
Second defining curve Specifies an object and start point for the sweep of
the new mesh object.

Enlarges or reduces selected objects, keeping the proportions of the object the
same after scaling.
916 | Chapter 2 Commands
Access Methods
Button
Toolbar: Drafting tool set Move/Rotate/Scale tool group Scale
Menu: Modify Scale
Shortcut menu: Select the objects to scale. Right-click in the drawing area
and click Scale.
Summary
To scale an object, specify a base point and a scale factor. The base point acts
as the center of the scaling operation and remains stationary. A scale factor
greater than 1 enlarges the object. A scale factor between 0 and 1 shrinks the
object.
List of Prompts
The following prompts are displayed.
Select objects: Use an object selection method and press Enter when you
finish
Specify base point: Specify a point
The base point you specify identifies the point that remains in the same
location as the selected objects change size (and thus move away from the
stationary base point).
NOTE When you use the SCALE command with annotative objects, the position
or location of the object is scaled relative to the base point of the scale operation,
but the size of the object is not changed.
Commands | 917
Specify scale factor (page 918) or [Copy (page 918)/Reference
(page 918)]: Specify a scale, enter c, or enter r
Scale Factor Multiplies the dimensions of the selected objects by the specified
scale. A scale factor greater than 1 enlarges the objects. A scale factor between
0 and 1 shrinks the objects. You can also drag the cursor to make the object
larger or smaller.
Copy Creates a copy of the selected objects for scaling.
Reference Scales the selected objects based on a reference length and a specified
new length.

New Layer Name Dialog Box
Adds a custom prefix or suffix to layer names to help organize components
of a section block
932 | Chapter 2 Commands
Access Methods
Pointing device: In the Section Settings dialog box (page 927), Layer list,
click New Layer Name Settings.
Summary
By default, all section block geometry is placed on Layer 0 (zero). However,
you can specify suffix or prefix labels to help organize section block
components, such as intersection boundaries and fill. When the section block
is inserted, the section block components are placed on new layers whose
name combines the name of the layer that contains the sectioned object and
the prefix or suffix you specify. If the section plane includes objects on two
or more layers, two or more new object layers are created.
For example, suppose you create a suffix called _kitchen and then select
*ObjectByLayer*_kitchen in the Section Settings dialog box, under Intersection
Boundary. If you create a section block that bisects objects on the Walls and
Cabinetry layers, two new layers are created to contain the block geometry
for intersection boundaries: Walls_kitchen and Cabinetry_kitchen.
You can then easily modify the appearance of a set of block components by
changing their properties. If a property such as Color is set as an object override
in the Section Settings dialog box, you can change the property in that
location. If the property is set to ByLayer, you can change it in the Layers
palette (page 538).
List of Options
The following options are displayed.
Added Text Type Specifies whether or how identifying text is added to the
layer name for the section block component.
None. No additional text is added to the layer name. The section block
geometry is placed on the same layer as the original geometry.
Prefix. If the Layer property is specified as *ObjectByLayer* in the Section
Settings dialog box, the label is added in front of the layer name.
Suffix. If the Layer property is specified as *ObjectByLayer* in the Section
Settings dialog box, the label is added to the end of the layer name.
Added Text
Specifies identifying text to be added to the name of the layer that contains
the component geometry when the section block is inserted.

Face: Extrude
Extrude Extends a 3D solid face in the X, Y, or Z direction. You can change
the shape of the object by moving its faces.
Entering a positive value extrudes the face outward; entering a positive taper
angle bevels the edges to the face. The Path option extrudes the face along a
selected line or curve. For major changes along a curve, consider using the
Sweep command.
Commands | 957
Select faces. Specifies which faces to modify.
Undo (page 958)
Remove (page 958)
Remove Removes previously selected faces from the selection set.
Remove faces. Removes the selected face from the solid object.
Undo (page 958)
Add (page 959)
All (page 959)
Undo Cancels the selection of the faces you added most recently to the
selection set and redisplays the prompt.

Add Adds faces you select to the selection set.
Undo (page 958)
Remove (page 958)
All (page 959)
All Selects all faces and adds them to the selection set.
Select faces. Selects specific faces (instead of all of them).
Undo (page 958)
Remove (page 958)
Commands | 959
Height of extrusion Sets the direction and distance of the extrusion. Entering
a positive value extrudes the face in the direction of its normal. Entering a
negative value extrudes the face in the direction opposite to its normal.
Angle of taper for extrusion. Specify an angle between -90 and +90
degrees.
Tapering the selected face with a positive angle tapers the face in, and a
negative angle tapers the face out. The default angle, 0, extrudes the face
perpendicular to its plane. All selected faces in the selection set are tapered
to the same value. If you specify a large taper angle or height, you can
cause the face to taper to a point before it reaches the extrusion height.
Path Sets a path for the extrusion path based on a specified line or curve. All
the profiles of the selected face are extruded along the chosen path to create
the extrusion.
Select an extrusion path.
960 | Chapter 2 Commands
Lines, circles, arcs, ellipses, elliptical arcs, polylines, or splines can be paths.
The path should not lie on the same plane as the face, nor should it have
areas of high curvature.
The extruded face starts from the plane of the profile and ends on a plane
perpendicular to the path at the path's endpoint. One of the endpoints of
the path should be on the plane of the profile; if not, the path is moved
to the center of the profile.
If the path is a spline, the path should be perpendicular to the plane of
the profile and at one of the endpoints of the path. If not, the profile is
rotated to be perpendicular to the spline path. If one of the endpoints of
the spline is on the plane of the face, the face is rotated about the point;
otherwise, the spline path is moved to the center of the profile and the
profiles are rotated about its center.
If the path contains segments that are not tangent, the object is extruded
along each segment and then the joint along the plane is mitred, bisecting
the angle formed by the segments. If the path is closed, the profile lies on
the miter plane. This allows the start and end sections of the solid to match
up. If the profile is not on the miter plane, the path is rotated until it is
on the miter plane.
Face: Move

SOLPROF
Creates 2D profile images of 3D solids for display in a layout viewport.
Access Methods
Menu: Draw 3D Modeling Setup Profile
Summary
The selected 3D solids are projected onto a 2D plane parallel with the current
layout viewport. The resulting 2D objects are generated on separate layers for
hidden and visible lines and are displayed only in that viewport.
List of Prompts
The following prompts are displayed.
Select objects: Use an object selection method
Display hidden profile lines on separate layer? [Yes (page
973)/No (page 974)] <Y>: Enteryorn, or press Enter
Yes Generates only two blocks: one for the visible lines and one for the hidden
lines of the entire selection set. When you generate hidden lines, solids can
partially or completely hide other solids. The visible profile block is drawn in
the BYLAYER linetype, and the hidden profile block is drawn in the HIDDEN
linetype (if loaded). The visible and hidden profile blocks are placed on
uniquely named layers using the following naming conventions:
PV-viewport handle for the visible profile layer
Commands | 973
PH-viewport handle for the hidden profile layer
For example, if you create a profile in a viewport whose handle is 4B, the
blocks containing the visible lines are inserted on layer PV-4B, and the block
containing the hidden lines (if requested) is inserted on layer PH-4B. If these
layers do not exist, the command creates them. If the layers do exist, the
blocks are added to the information already on the layers.
NOTE To determine the handle of a viewport, select the viewport while in paper
space and use the LIST (page 581) command. Choose a layout tab to move from
model space to paper space.
SOLPROF does not change the display of layers; if you want to view only the
profile lines that you have created, turn off the layer containing the original
solid (usually the current layer).
No Treats all profile lines as visible lines and creates a block for the profile
lines of each selected solid. All profile lines for each solid in the selection set
are generated, even if a solid is partially or completely obscured by another
solid. The visible profile blocks are drawn in the same linetype as the original
solid and placed on a uniquely named layer using the naming convention
described under the Yes option.
NOTE Solids that overlap each other (share some common volume) produce
dangling edges if you request hidden-line removal. This happens because the
edges must be broken at the point where they enter another solid to separate
them into visible and hidden portions. You can eliminate dangling edges by
combining the overlapping solids (using UNION (page 1092)) before generating a
profile.
Yes Creates the profile lines with 2D objects.
The 3D profile is projected onto a plane normal to the viewing direction and
passing through the origin of the UCS. SOLPROF cleans up the 2D profile by
eliminating lines that are parallel to the viewing direction and by converting
arcs and circles that are viewed on edge into lines.
974 | Chapter 2 Commands
No Creates the profile lines with 3D objects.
The next prompt determines whether tangential edges are displayed. A
tangential edge is the transition line between two tangent faces. It's the
imaginary edge at which two faces meet and are tangent. For example, if you
fillet the edge of a box, tangential edges are created where the cylindrical face
of the fillet blends into the planar faces of the box. Tangential edges are not
shown for most drafting applications.

SOLVIEW places the viewport objects on the VPORTS layer, which it creates
if it does not already exist. The view-specific information that is saved with
each viewport you create is used by SOLDRAW (page 954) to generate the final
drawing view.
SOLVIEW creates layers that SOLDRAW uses to place the visible lines and
hidden lines for each view, view name-VIS, view name-HID, view name-HAT,
and a layer where you can place dimensions that are visible in individual
viewports, view name-DIM.
WARNING The information stored on these layers is deleted and updated when
you run SOLDRAW (page 954). Do not place permanent drawing information on
these layers.
UCS
Creates a profile view relative to a user coordinate system. If no viewports
exist in your drawing, the UCS option is a good way to create an initial
viewport from which other views can be created. All other SOLVIEW options
require an existing viewport.
You have the option of using the current UCS or a previously saved one as
the profile plane. The viewport projection is created parallel to the XY plane
of the UCS with the X axis facing right and the Y axis upward.
976 | Chapter 2 Commands
Named Uses the XY plane of a named UCS to create a profile view.
Enter the name of the UCS you want to use and the scale of your view. Entering
a scale is equivalent to zooming your viewport by a factor relative to paper
space.
The center is based on the current model space extents.
World Uses the XY plane of the WCS to create a profile view.
Enter the name of the UCS you want to use and the scale of your view. Entering
a scale is equivalent to zooming your viewport by a factor relative to paper
space.
The center is based on the current model space extents.
?List Named UCSs Lists the names of existing user coordinate systems. The
list is filtered using the wild-card combinations you enter (wild-card characters
accepted by the UCS command are valid).
Current Uses the XY plane of the current UCS to create a profile view.
Enter the name of the UCS you want to use and the scale of your view. Entering
a scale is equivalent to zooming your viewport by a factor relative to paper
space.
The center is based on the current model space extents.
Commands | 977
Ortho
Creates a folded orthographic view from an existing view.
Once you select the side of the viewport you want to use for projecting the
new view, a rubber-band line perpendicular to the side of the viewport helps
you locate the center of the new view.
Auxiliary
Creates an auxiliary view from an existing view. An auxiliary view is one that
is projected onto a plane perpendicular to one of the orthographic views and
inclined in the adjacent view.
978 | Chapter 2 Commands
Two points define the inclined plane used for the auxiliary projection. Both
points must be located in the same viewport.
A rubber-band line perpendicular to the inclined plane helps you select the
center of the new viewport.
Section
Creates a drafting sectional view of solids, complete with cross-hatching. When
you use SOLDRAW (page 954) on a sectional view created with this option, it
creates a temporary copy of the solids and uses SLICE (page 946) to perform
the operation at the cutting plane that you define. SOLDRAW then generates
a profile of the visible half of the solids and discards the original copy. Finally
SOLDRAW sections the solids. Solids not crossing the cutting plane are
generated as full profiles. Because drafting standards recommend not drawing
hidden lines in sectional views, SOLVIEW freezes the View Name-HID layer.
Commands | 979
In the original viewport, specify two points to define the sectioning plane.
Define the viewing side by specifying a point on one side of the cutting plane.
Enter the scale of the new view. Entering a scale is equivalent to zooming your
viewport by a factor relative to paper space. The default value is a 1:1 scale,
which is equivalent to zoom 1.0xp.
At the next prompt, specify the center of the new viewport. If you accepted
the default scale (by pressing Enter), a rubber-band line perpendicular to the
sectioning plane helps you locate the center of the new view. Otherwise, you
can place the view anywhere.

SPLINE
Creates a smooth curve that passes through or near a set of fit points, or that
is defined by the vertices in a control frame.
Access Methods
Button
Toolbar: Drafting tool set Open Shapes tool group Spline
Menu: Draw Spline Fit Points
Menu: Draw Spline Control Vertices
Summary
SPLINE creates curves called nonuniform rational B-splines (NURBS), referred to
as splines for simplicity.
Splines are defined either with fit points, or with control vertices. By default,
fit points coincide with the spline, while control vertices define a control frame.
Control frames provide a convenient method to shape the spline. Each method
has its advantages.
988 | Chapter 2 Commands
To display or hide the control vertices and control frame, select or deselect
the spline, or use CVSHOW (page 247) and CVHIDE (page 242).
For splines created with control vertices, you can display the control frame
by selecting the spline.
List of Prompts
The prompts that display depend on whether you create a spline with fit
points or with control vertices.
For splines created with the fit point method:
Specify first point or [Method (page ?)/Degree (page
992)/Object (page ?)]:
For splines created with the control vertices method:
Specify first point or [Method (page ?)/Knots (page 991)/Ob-
ject (page ?)]:
First Point
Specifies the first point of the spline, either the first fit point or the first control
vertex, depending on the current method.
Method
Controls whether the spline is created with fit points or with control vertices.
(SPLMETHOD (page 1447) system variable)
Fit Creates a degree 3 (cubic) B-spline by specifying fit points that the spline
must pass through. When the tolerance value is greater than 0, the spline
must be within the specified tolerance distance from each point.
Changing the Method updates the SPLMETHOD (page 1447) system variable.
Control Vertices Creates a spline by specifying control vertices. Use this
method to create splines of degree 1 (linear), degree 2 (quadratic), degree 3
Commands | 989
(cubic), and so on up to degree 10. Adjusting the shape of a spline by moving
control vertices often provides better results than moving fit points.
This is the preferred method if you are creating geometry to use with 3D
NURBS surfaces.
Object
Converts 2D or 3D quadratic or cubic spline-fit polylines to equivalent splines.
The original polyline is retained or discarded depending on the setting of the
DELOBJ (page 1213) system variable.
Next Point
Creates additional spline segments until you press Enter.
Undo
Removes the last specified point.
Close
Closes the spline by defining the last point to be coincident with the first. By
default, closed splines are periodic, maintaining curvature continuity (C2)
along the entire loop.
990 | Chapter 2 Commands
Options for Splines with Fit Points
The following options are specific to the fit point method.
Knots Specifies the knot parameterization, one of several computational methods
that determines how the component curves between successive fit points
within a spline are blended. (SPLKNOTS (page 1447) system variable)
Chord (or Chord-Length method). Spaces the knots connecting each
component curve to be proportional to the distances between each
associated pair of fit points. An example is the green curve in the
illustration.
Square Root (or Centripetal method). Spaces the knots connecting each
component curve to be proportional to the square root of the distance
between each associated pair of fit points. This method usually produces
gentler curves. An example is the blue curve in the illustration.
Uniform (or Equidistant method). Spaces the knots of each component
curve to be equal, regardless of the spacing of the fit points. This method
often produces curves that overshoot the fit points. An example is the
magenta curve in the illustration.
Start Tangency Specifies a tangent condition on the starting point of the
spline.
Commands | 991
End Tangency Specifies a tangent condition on the ending point of the spline.
Tolerance Specifies the distance by which the spline is allowed to deviate
from the specified fit points. A tolerance value of 0 requires the resulting spline
to pass directly through the fit points. The tolerance value applies to all fit
points except the starting and ending fit points, which always have a tolerance
of 0.
Options for Splines with Control Vertices
The following option is specific to the control vertices (CV) method.
(SPLMETHOD (page 1447) system variable)
Degree Sets the polynomial degree of the resulting spline. Use this option to
create splines of degree 1 (linear), degree 2 (quadratic), degree 3 (cubic), and
so on up to degree 10.

SPLINEDIT
Modifies the parameters of a spline or converts a spline-fit polyline to a spline.
Access Methods
Menu: Modify Object Spline
Shortcut menu: Select a spline to edit. Right-click in the drawing area and
click Spline.
Summary
Modifies the data that defines a spline, such as the number and weight of
control vertices, the fit tolerance, and the starting and ending tangents.
NOTE
SPLINEDIT automatically converts spline-fit polylines to splines even if you
immediately exit SPLINEDIT after selecting the spline-fit polyline.
The data that defines a spline is represented in one of two formats: as a control
frame or as fit points. The format can change depending on how the spline
was originally created, the options selected from the grip menus, or the options
used in SPLINEDIT.
You can change any of following data:
Control frame data consists of control vertices, the polynomial degree of
the spline, and the weights assigned to each control vertex.
Fit data consists of fit points, knot parameterization, the fit tolerance, and
the tangents at the endpoints of the spline.
NOTE
Switching from displaying control vertices to fit points automatically changes
the selected spline to degree 3. Splines originally created using higher-degree
equations will likely change shape as a result. In addition, if the spline was
created using a positive tolerance value, the fit points will be relocated to the
knots on the spline, and the tolerance value is reset to 0.
List of Prompts
The following prompts are displayed.
Select spline:

Close/Open
One of the following options displays, depending on whether the selected
spline is open or closed. An open spline has two endpoints, while a closed
spline forms a loop.
Close Closes an open spline by defining the last point to be coincident with
the first. By default, closed splines are periodic, maintaining curvature
continuity (C2) along the entire curve.
Open Opens a closed spline by removing the final curve segment between
the first and last points specified when the spline was originally created.
Join
Combines a selected spline with other splines, lines, polylines, and arcs at
coincident endpoints to form a larger spline. Objects are joined with kinks at
the points where they are joined (C0 continuity).
Fit Data
Edits fit point data using the following options:
Enter a fit data option [Add (page ?)/Close (page ?)Delete (page ?)/Kink
(page ?)/Move (page ?)/Purge (page ?)/Tangents (page ?)/toLerance (page
?)/eXit (page ?)] <eXit>:
Add
Adds fit points to the spline.
After selecting a fit point, specify a new fit point to be added to the spline in
the direction of the next fit point, which is automatically highlighted.
If you select the last fit point on an open spline, the new fit point is added to
the end of the spline.
If you select the first fit point on an open spline, you have the option of
specifying whether the new fit point is added before or after the first point.
994 | Chapter 2 Commands
Close/Open
One of the following options displays, depending on whether the selected
spline is open or closed. An open spline has two endpoints, while a closed
spline forms a loop.
Close Closes an open spline by defining the last point to be coincident with
the first. By default, closed splines are periodic, maintaining curvature
continuity (C2) along the entire curve.
Open Opens a closed spline by removing the final curve segment between
the first and last points specified when the spline was originally created.
Delete
Removes selected fit points from a spline.
Kink

NOTE
When the LIGHTINGUNITS system variable is set to 1 or 2, the Attenuation
option has no affect on the creation of the light. It is only maintained for
scripting compatibility.
Name
Specifies the name of the light. You can use uppercase and lowercase letters,
numbers, spaces, hyphens (-), and underscores (_) in the name.
998 | Chapter 2 Commands
Intensity/Intensity Factor
Sets the intensity or brightness of the light. The range is 0.00 to the maximum
value that is supported by your system.
Hotspot
Specifies the angle that defines the brightest cone of light, which is known to
lighting designers as the beam angle. This value can range from 0 to 160
degrees or the equivalent values based on AUNITS (page 1177).
Falloff
Specifies the angle that defines the full cone of light, which is also known as
the field angle. This value can range from 0 to 160 degrees. The default is 50
degrees or the equivalent values based on AUNITS (page 1177). The falloff angle
must be greater than or equal to the hotspot angle.
Status
Turns the light on and off.
Photometry
Photometry is the measurement of the luminous intensities of visible light
sources. Photometry is available when the LIGHTINGUNITS system variable
is set to 1 or 2.
In photometry, luminous intensity is a measure of the perceived power emitted
by a light source in a particular direction. Luminous flux is the perceived
power per unit of solid angle. The total luminous flux for a lamp is the
perceived power emitted in all directions. Luminance is the total luminous
flux incident on a surface, per unit area.
Intensity Enter an intensity value in candelas, the perceived power in a
luminous flux value, or illuminance value for the total luminous flux incident
on a surface.
Candela (symbol: cd) is the SI unit of luminous intensity (perceived power
emitted by a light source in a particular direction). Cd/Sr
Lux (symbol: lx) is the SI unit of illuminance. Lm/m^2
Foot-candle (symbol: fc) is the American unit of illuminance. Lm/ft^2
Enter f to specify the perceived power in a luminous flux value.
If you enter i, you can specify the intensity of the light based on an
illuminance value.
The illuminance value can be specified in either lux or foot-candles. Enter d
to specify a distance to use to calculate illuminance.

names, or an asterisk (*) to display all the possible choices.
If you enter k, you can specify the color of the light based on a Kelvin
temperature value.
Shadow
Makes the light cast shadows.
Off Turns off display and calculation of shadows for the light. Turning shadows
off increases performance.
Sharp Displays shadows with sharp edges. Use this option to increase
performance.
Soft Mapped Displays realistic shadows with soft edges.
Map Size. Specifies the amount of memory to use to calculate the shadow
map.
Softness. Specifies the softness to use to calculate the shadow map.
Soft Sampled Displays realistic shadows with softer shadows (penumbra)
based on extended light sources.
Specify the shape of the shadow by entering s and then the dimensions of
the shape. (For example, the radius of the sphere or the length and width of
a rectangle.)
Specify the sample size by entering a.
Specify the visibility of the shape by for the shadow by entering v.
Attenuation
Attenuation Type Controls how light diminishes over distance. The farther
away an object is from a spotlight, the darker the object appears. Attenuation
is also known as decay.
None. Sets no attenuation. Objects far from the spotlight are as bright as
objects close to the light.
Inverse Linear. Sets attenuation to be the inverse of the linear distance
from the light. For example, at a distance of 2 units, light is half as strong
as at the spotlight; at a distance of 4 units, light is one quarter as strong.
The default value for inverse linear is half the maximum intensity.
Inverse Squared. Sets attenuation to be the inverse of the square of the
distance from the light. For example, at a distance of 2 units, light is one
quarter as strong as at the spotlight; at a distance of 4 units, light is one
sixteenth as strong.
Use Limits Specifies whether to use limits.
1000 | Chapter 2 Commands
Attenuation Start Limit Specifies the point where light starts as an offset
from the center of the light. The default is 0.
Attenuation End Limit Specifies the point where light ends as an offset from
the center of the light. No light is cast beyond this point. Setting an end limit
increases performance where the effect of lighting is so minimal that the
calculations are wasted processing time.
Color/Filter Color
Controls the color of the light.
True Color Specifies a True Color. Enter in the format R,G,B (red, green, blue).
Index Specifies an ACI (AutoCAD Color Index) color.
HSL Specifies an HSL (hue, saturation, luminance) color.

STLOUT
Stores solids in an ASCII or binary file.
Summary
The FACETRES (page 1295) system variable determines how the solid is
triangulated. A higher value creates a finer mesh that more accurately
represents the model. This also results in a much larger file.
Select solids or watertight meshes
You can select blocks or external references (xrefs) that contain solids or
watertight meshes. Only solids and watertight meshes of the selected blocks
of xrefs are included in the STL file. All other geometry is discarded.
Create a binary STL file? [Yes/No] <Yes>: To create a STL file,
enteryor press Enter. To create an ASCII file, entern
The Create STL File Dialog Box (page 1004) displays.
Commands | 1003
The file is created with the .stl file name extension. The STL file format is
compatible with stereolithography apparatus (SLA). The solid data is transferred
to the SLA as a faceted representation of the model. The facets consist of a set

TABSURF
Creates a mesh from a line or curve that is swept along a straight path.
Access Methods
Menu: Draw 3D Modeling Meshes Tabulated Mesh
Summary
Select a line, arc, circle, ellipse, or polyline to sweep in a straight path. Then
select a line or polyline to determine the first and last points of a vector that
indicates the direction and length of the polygon mesh.
The MESHTYPE (page 1369) system variable sets which type of mesh is created.
Mesh objects are created by default. Set the variable to 0 to create legacy
polyface or polygon mesh.
For polygon meshes, TABSURF constructs a 2 by n mesh, where n is determined
by the SURFTAB1 (page 1454) system variable. The M direction of the mesh is
always 2 and lies along the direction vector. The N direction lies along the
path curve. If the path curve is a line, arc, circle, ellipse, or spline-fit polyline,
tabulation lines are drawn that divide the path curve into intervals of equal
size set by SURFTAB1. If the path curve is a polyline that has not been spline
fit, tabulation lines are drawn at the ends of straight segments, and each arc
segment is divided into intervals set by SURFTAB1.
Commands | 1039
List of Prompts
The following prompts are displayed.
Object for path curve Specifies which object is swept along the path.
The path curve defines the approximated surface of the polygon mesh. It can
be a line, arc, circle, ellipse, or 2D or 3D polyline. The mesh is drawn starting
at the point on the path curve closest to the selection point.
Object for direction vector. Specifies a line or open polyline that defines the
direction of the sweep.
Only the first and last points on a polyline are considered, and intermediate
vertices are ignored. The direction vector indicates the direction and length
of the shape to be extruded. The end selected on the polyline or line determines
the direction of the extrusion. The original path curve is drawn with wide
lines to help you visualize how the direction vector dictates the construction
of a tabulated mesh.

NOTE
When the LIGHTINGUNITS system variable is set to 1 or 2, the Attenuation
option has no affect on the creation of the light. It is only maintained for
scripting compatibility.
Name
Specifies the name of the light.
Intensity/Intensity Factor
Sets the intensity or brightness of the light.
Status
Turns the light on and off.
Photometry
Photometry is available when the LIGHTINGUNITS system variable is set to
1 or 2. Photometry is the measurement of the luminous intensities of visible
light sources.
In photometry, luminous intensity is a measure of the perceived power emitted
by a light source in a particular direction. Luminous flux is the perceived
power per unit of solid angle. The total luminous flux for a lamp is the
perceived power emitted in all directions. Luminance is the total luminous
flux incident on a surface, per unit area.
Commands | 1041
Intensity Enter an intensity value in candelas, the perceived power in a
luminous flux value, or illuminance value for the total luminous flux incident
on a surface.
Candela (symbol: cd) is the SI unit of luminous intensity (perceived power
emitted by a light source in a particular direction). Cd/Sr
Lux (symbol: lx) is the SI unit of illuminance. Lm/m^2
Foot-candle (symbol: fc) is the American unit of illuminance. Lm/ft^2
Enter f to specify the perceived power in a luminous flux value.
If you enter i, you can specify the intensity of the light based on an
illuminance value.
The illuminance value can be specified in either lux or foot-candles. Enter d
to specify a distance to use to calculate illuminance.
Color Specify the color of the light based on a color name or a Kelvin
temperature.
Enter ? to display a list of color names. Enter a text string using wild card
characters to display a partial listing of color names, or an asterisk (*) to display
all the possible choices.
If you enter k, you can specify the color of the light based on a Kelvin

performance.
Soft Mapped Displays realistic shadows with soft edges.
Map Size Specifies the amount of memory that should be used to calculate
the shadow map.
Softness Specifies the softness to use to calculate the shadow map.
Soft Sampled Displays realistic shadows with softer shadows (penumbra)
based on extended light sources.
Shape Specify the shape of the shadow by entering s and then the dimensions
of the shape. (For example, the radius of the sphere or the length and width
of a rectangle.)
1042 | Chapter 2 Commands
Attenuation
Attenuation Type Controls how light diminishes over distance. The farther
away an object is from a point light, the darker the object appears. Attenuation
is also known as decay.
None. Sets no attenuation. Objects far from the point light are as bright
as objects close to the light.
Inverse Linear. Sets attenuation to be the inverse of the linear distance
from the light. For example, at a distance of 2 units, light is half as strong
as at the point light; at a distance of 4 units, light is one quarter as strong.
The default value for inverse linear is half the maximum intensity.
Inverse Squared. Sets attenuation to be the inverse of the square of the
distance from the light. For example, at a distance of 2 units, light is one
quarter as strong as at the point light; at a distance of 4 units, light is one
sixteenth as strong.
Use Limits Specifies whether to use limits or not.
Attenuation Start Limit Specifies the point where light starts as an offset
from the center of the light.
Attenuation End Limit Specifies the point where light ends as an offset from
the center of the light. No light is cast beyond this point. Setting an end limit
increases performance where the effect of lighting is so minimal that the
calculations are wasted processing time.
Color/Filter Color
Controls the color of the light.
True Color Specifies a True Color. Enter in the format R,G,B (red, green, blue).
Index Specifies an ACI (AutoCAD Color Index) color.
HSL Specifies an HSL (hue, saturation, luminance) color.
Color Book Specifies a color from a color book.
Exit

Displays information about the drawing's current spatial index.
Access Methods
Command entry: 'treestat for transparent use
Summary
The program indexes objects in a region by recording their positions in space.
The result is called a spatial index. The spatial index is tree structured and has
branching nodes to which objects are attached. The index has two major
branches. The paper space branch is called a quad-tree and treats objects as
two-dimensional. The model space branch is called an oct-tree and treats
objects as either two- or three-dimensional. The model space branch can also
be changed to a quad-tree when you are working on two-dimensional drawings.
TREESTAT displays information about each branch. The most important
information is in the first two lines of the reportnumber of nodes, number
of objects, maximum depth of the branch, and average number of objects per
node.
If REDRAW (page 869) and object selection are very slow, you can improve
their performance. For example, if there are 50 megabytes of memory available
1066 | Chapter 2 Commands
and the current drawing has 50,000 objects with only 1,000 nodes in the index
tree, increase the TREEDEPTH (page 1472) value to improve performance.
Each node consumes about 80 bytes of memory. The fewer objects per node
of the oct-tree, the better the performance.

1068 | Chapter 2 Commands
Shift-Select to Extend
Extends the selected objects rather than trimming them. This option provides
an easy method to switch between trimming and extending.
Fence
Selects all objects that cross the selection fence. The selection fence is a series
of temporary line segments that you specify with two or more fence points.
The selection fence does not form a closed loop.
Crossing
Selects objects within and crossing a rectangular area defined by two points.
NOTE
Some crossing selections of objects to be trimmed are ambiguous. TRIM resolves
the selection by following along the rectangular crossing window in a clockwise
direction from the first point to the first object encountered.
Project
Specifies the projection method used when trimming objects.
None Specifies no projection. The command trims only objects that intersect
with the cutting edge in 3D space.
UCS Specifies projection onto the XY plane of the current UCS. The command
trims objects that do not intersect with the cutting edge in 3D space.
Commands | 1069
View Specifies projection along the current view direction. The command
trims objects that intersect the boundary in the current view.
Edge
Determines whether an object is trimmed at another object's extrapolated
edge or only to an object that intersects it in 3D space.
Extend Extends the cutting edge along its natural path to intersect an object
in 3D space.
No Extend Specifies that the object is trimmed only at a cutting edge that
intersects it in 3D space.
NOTE
When trimming hatches, do not set Edge to Extend. If you do, gaps in the
trim boundaries will not be bridged when trimming hatches, even when the
gap tolerance is set to a correct value.

If you specify a single point, the origin of the current UCS shifts without
changing the orientation of the X, Y, and Z axes.
If you specify a second point, the UCS rotates to pass the positive X axis
through this point.
If you specify a third point, the UCS rotates around the new X axis to
define the positive Y axis.
1072 | Chapter 2 Commands
The three points specify an origin point, a point on the positive X axis, and
a point on the positive XY plane.
NOTE If you do not specify a Z coordinate value when entering a coordinate, the
current Z value is used.
TIP You can also select and drag the UCS icon origin grip directly to a new location,
or choose Move Origin Only from the origin grip menu.

123d45'56.7"
Surveyor's units show angles as bearings, using N or S for north or south,
degrees/minutes/seconds for how far east or west the angle is from direct north
or south, and E or W for east or west; for example:
N 45d0'0" E
The angle is always less than 90 degrees and is displayed in the
degrees/minutes/seconds format. If the angle is precisely north, south, east,
or west, only the single letter representing the compass point is displayed.
Clockwise
Calculates positive angles in the clockwise direction. The default direction for
positive angles is counterclockwise.
When prompted for an angle, you can point in the desired direction or enter
an angle regardless of the setting specified for Clockwise.

be specified from the list of options. If Insertion Scale is set to Unitless, a
warning message is displayed informing you that the rendered output might
not be as expected.
Commands | 1097
Insertion Scale
Controls the unit of measurement for blocks and drawings that are inserted
into the current drawing. A block or a drawing that is created with units that
are different from the units specified with this option is scaled when inserted.
The insertion scale is the ratio of the units used in the source block or drawing
and the units used in the target drawing. Select Unitless to insert the block
without scaling it to match the specified units.

Delete Deletes one or more named views.
Orthographic Restores the predefined orthographic view you specify to the
current viewport.
1104 | Chapter 2 Commands
The view orientation of the specified orthographic view is based on the UC-
SBASE (page 1477) system variable, which is set to the world coordinate system
by default. When one of the orthographic views is restored, the program zooms
to the extents in the current viewport.
Restore Restores the view you specify to the current viewport. If a UCS setting
was saved with the view, it is also restored.
The center point and magnification of the saved view are also restored. If you
restore a model space view while working in paper space, you are prompted
to select a viewport in which to restore that view.
Select the viewport by clicking its border. The viewport you select must be on
and active. The program switches to model space and restores the view in the

VIEWRES
Sets the resolution for objects in the current viewport.
Summary
The model is regenerated.
VIEWRES controls the appearance of circles, arcs, splines, and arced polylines
using short vectors. The greater the number of vectors, the smoother the
appearance of the circle or arc. For example, if you create a very small circle
and then zoom in, it might appear to be a polygon. Using VIEWRES to increase
the zoom percentage and regenerate the drawing updates and smooths the
circle's appearance.
NOTE
Increasing the zoom percentage in VIEWRES may increase the time it takes
to regenerate the drawing.
When a named (paper space) layout is made current for the first time and a
default viewport is created in the layout, the viewing resolution for this initial
viewport is the same as the viewing resolution for the Model layout viewport.
The VIEWRES setting is saved in the drawing. To change the default for new
drawings, consider specifying the VIEWRES setting in the template files on
which you base your new drawings.

All Zooms to display all visible objects and visual aids.
Adjusts the magnification of the drawing area to accommodate the extents
of all visible objects in the drawing, or visual aids such as the grid limits (the
LIMITS (page 573) command), whichever is larger.
In the illustration on the right, the grid limits are set to a larger area than the
extents of the drawing.
Because it always regenerates the drawing, you cannot use ZOOM All
transparently.
Center Zooms to display a view defined by a center point and a magnification
value or a height. A smaller value for the height increases the magnification.
A larger value decreases the magnification. Not available in perspective
projection.
1154 | Chapter 2 Commands
Dynamic Pans and zooms using a rectangular view box. The view box
represents your view, which you can shrink or enlarge and move around the
drawing. Positioning and sizing the view box pans or zooms to fill the viewport
with the view inside the view box. Not available in perspective projection.
To change the size of the view box, click, resize it, and click again to accept
the new size of the view box.
To pan with the view box, drag it to the location you want and press Enter.
Extents Zooms to display the maximum extents of all objects.
The extents of each object in the model are calculated and used to determine
how the model should fill the window.
Previous Zooms to display the previous view. You can restore up to 10 previous
views.
Commands | 1155
NOTE
If you change the visual style, the view is changed. If you enter ZOOM Previous,
it restores the previous view, which is shaded differently but not zoomed
differently.
Scale Zooms to change the magnification of a view using a scale factor.
Enter a value followed by x to specify the scale relative to the current view.
Enter a value followed by xp to specify the scale relative to paper space
units.
For example, entering .5x causes each object to be displayed at half its current
size on the screen.
Entering .5xp displays model space at half the scale of paper space units. You
can create a layout with each viewport displaying objects at a different scale.
Enter a value to specify the scale relative to the grid limits of the drawing.
(This option is rarely used.) For example, entering 2 displays objects at twice
the size they would appear if you were zoomed to the limits of the drawing.
Window Zooms to display an area specified by a rectangular window.
With the cursor, you can define an area of the model to fill the entire window.
1156 | Chapter 2 Commands
Object Zooms to display one or more selected objects as large as possible and
in the center of the view. You can select objects before or after you start the
ZOOM command.
Real Time Zooms interactively to change the magnification of the view.
The cursor changes to a magnifying glass with plus (+) and minus (-) signs.
See Zoom Shortcut Menu (page 1157) for a description of the options that are
available while zooming in real time.
Holding down the pick button at the midpoint of the window and moving
vertically to the top of the window zooms in to 100%. Conversely, holding
the pick button down at the midpoint of the window and moving vertically
to the bottom of the window zooms out by 100%.
When you reach the zoom-in limit, the plus sign in the cursor disappears,
indicating that you can no longer zoom in. When you reach the zoom-out
limit, the minus sign in the cursor disappears, indicating that you can no
longer zoom out.
When you release the pick button, zooming stops. You can release the pick
button, move the cursor to another location in the drawing, and then press
the pick button again and continue to zoom the display from that location.
To exit zooming, press Enter or Esc.

Command Modifiers
You can use command modifiers to help you locate points or select objects
while a command is in progress. Use the Coordinate Filter, Direct Distance
Entry, From, MTP, and Tracking command modifiers at any prompt that requires
point specification. Use the Selection Mode command modifiers at any prompt
that requires object selection.
Coordinate Filters (Command Modifier)
Combines X, Y, and Z values from different points to specify a single point
Command entry: Enter .x, .y, .xy, .xz, or .yz
At any prompt for locating a point, you can enter point filters to specify a single
coordinate by extracting the X, Y, and Z values of several points. In the following
example, the start point for the line has a coordinate constructed from the X
value of the midpoint of the first object you select, with the Y and Z values of
the midpoint of the second object you select.
Command: line
Specify first point: .x

Direct Distance Entry (Command Modifier)
Locates the next point at a specified distance in the direction of your cursor
Command entry: At a prompt to locate a point, enter a numeric value
With direct distance entry, you can quickly specify a point relative to the last
point you entered. At any prompt for a point location, you move the cursor
first to specify the direction, and then enter a numeric distance.
In the following example, the second point for the line will be located 5 units
toward the direction of the cursor. The direct distance that you enter is
measured along the path from the last point to the current location of the
cursor. This feature is usually used with Ortho or Snap mode turned on.
Command: line
Specify first point: Specify a point
Specify next point: Move the cursor in the desired direction and enter 5
NOTE
The direct distance entry method is not available while you are using temporary
override keys for Ortho, object snap tracking, or polar tracking.
See also:
Enter Direct Distances
FROM (Command Modifier)
Locates a point offset from a reference point within a command.
Toolbar: Object Snap
Command entry: At a prompt to locate a point, enter from
Base Point: Specify a point to use as a base point
of <offset>: Enter a relative offset
At a prompt for locating a point, enter from, and then enter a temporary
reference or base point from which you can specify an offset to locate the next
1160 | Chapter 3 Command Modifiers
point. Enter the offset location from this base point as a relative coordinate,
or use direct distance entry (page 1160).
NOTE
You cannot use this method during dragging in commands such as MOVE
and COPY. Specifying an absolute coordinate, either by keyboard entry or
with a pointing device, cancels the FROM command.
See also:
Offset from Temporary Reference Points
MTP (Command Modifier)
Locates the midpoint between two points.
Command entry: At a prompt to locate a point, enter mtp
The midpoint between two points (MTP) command modifier can be used with
running object snaps or object snap overrides. (OSNAP (page 743) command)
At any Command prompt to locate a point, enter mtp or m2p.
First point of mid: Specify a point
Second point of mid: Specify a second point
TRACKING (Command Modifier)
Locates a point from a series of temporary points.
Command entry: At a prompt to locate a point, enter tracking
Tracking turns on Ortho mode and can be used with Snap mode.
At any prompt to locate a point, enter tracking, track, or tk.
First tracking point: Specify a location or distance
Next point (Press ENTER to end tracking): Specify a second location
or distance
Tracking specifies a series of temporary points, each offset from the previous
one. Thus, you specify a new point location from a series of directions and
distances. To determine the location of each temporary point, you can use
direct distance entry (page 1160). First move the cursor to specify the direction,
and then enter a numeric distance.
Command Modifiers | 1161
Alternatively, tracking can establish a new point by combining the X and Y
values of two specified points. You can specify these two points in any order,
depending on the cursor direction after the first point. Direct distance entry
specifies a distance in the direction of the current location of your cursor.
Coordinate filters (page 1159) combine X, Y, and Z values from different points
into a single point. Relative coordinate entry locates a point relative to the
last point entered.
You can also access tracking by holding down SHIFT and right-clicking to
display the object snap shortcut menu.
See also:
Track to Offset Point Locations (Tracking)
Object Snaps (Command Modifier)
Specifies a precise point at a location on an object.
Command entry: Within a command, at a prompt to locate a point, specify
an object snap
When you specify an object snap, the cursor snaps to the specified point on
an object closest to the center of the cursor. By default, a marker and a tooltip
are displayed when you move the cursor over the object snap location on an
object.
Specify a Single Object Snap
If you specify a single object snap, it stays in effect only for the next point
you specify.
You can specify an object snap with any of the following methods:
Enter a object snap by typing its name. To see a list of valid object snaps,
refer to the OSNAP (page 743) command or the Drafting Settings Dialog
Box (page 364).
Click an object snap from the Object Snap toolbar.
Click an object snap from the Object Snap shortcut menu. You can diisplay
this shortcut menu by pressing SHIFT while you right-click.
1162 | Chapter 3 Command Modifiers
Use Running Object Snaps
Using the OSNAP (page 743) or DSETTINGS (page 363) commands, you can
specify a set of running object snaps. Running object snaps are one or more
object snaps that remain in effect as you work.
To turn running object snaps on and off, click the OSNAP button on the
status bar or press F3.
Press TAB to cycle through the object snap possibilities before you specify
the point.
To turn off running object snaps for the next point only, specify the None
object snap.
Selection Modes (Command Modifier)
Controls how you create selection sets
Command entry: At a prompt to select objects, enter one of the valid selection
modes described in the SELECT command
The selection mode you enter remains active only for the current Select Objects
prompt.

DATE

VariesInitial value:
This value is represented as a Modified Julian Date (MJD), which is the Julian
day number and decimal fraction of a day in the format:
<Julian day number>.<Decimal fraction of a day>
The Modified Julian Date, conventionally called UT1, is a worldwide scientific
standard that assigns day numbers beginning at an essentially arbitrary date
and time of 12:00 a.m. on 1 January 4713 B.C. (B.C.E.). With this system, 4
July 1997 at 2:29:58 p.m. corresponds to 2450634.60387736, and 1 January
1998 at 12:00 noon corresponds to 2450815.50000000.
You can compute differences in date and time by subtracting the numbers
returned by DATE. To extract the seconds since midnight from the value
returned by DATE, use AutoLISP expressions:
(setq s (getvar "DATE"))
(setq seconds (* 86400.0 (- s (fix s))))
Because your computer clock provides the date and time, the DATE system
variable returns a true Julian date only if the system clock is set to UTC/Zulu
(Greenwich Mean Time). TDCREATE (page 1457) and TDUPDATE (page 1458) have
the same format as DATE, but their values represent the creation time and
last update time of the current drawing.

Creates non-associative dimension objects. The elements of the di-
mension are formed into a single object. If one of the definition
points of the dimension moves, the dimension is updated.
1
Creates associative dimension objects. The elements of the dimension
are formed into a single object, and one or more definition points

of the dimension are coupled with association points on geometric
objects. If the association point on the geometric object moves, the
dimension location, orientation, and value are updated.
DIMASSOC is not stored in a dimension style.
Drawings saved in a format previous to AutoCAD 2002 retain the setting of
the DIMASSOC system variable. When the drawing is reopened in AutoCAD
2002 or later, the dimension associativity setting is restored.

System Variables | 1239
Use MLEADERSCALE (page 1371) to scale multileader objects created with the
MLEADER (page 651) command.
A reasonable default value is computed based on the scaling between
the current model space viewport and paper space. If you are in
0.0
paper space or model space and not using the paper space feature,
the scale factor is 1.0.
A scale factor is computed that leads text sizes, arrowhead sizes,
and other scaled distances to plot at their face values.

DIMSCALE does not affect measured lengths, coordinates, or angles.
Use DIMSCALE to control the overall scale of dimensions. However, if the
current dimension style is annotative, DIMSCALE is automatically set to zero
and the dimension scale is controlled by the CANNOSCALE (page 1184) system

LAYOUTREGENCTL
Specifies how the display list is updated in the Model layout and named
layouts.
IntegerType:
RegistrySaved in:
2Initial value:
For each layout, the display list is updated either by regenerating the drawing
when you switch to that layout or by saving the display list to memory and
regenerating only the modified objects when you switch to that layout.
Changing the LAYOUTREGENCTL setting can improve performance.
The drawing is regenerated each time you switch tabs.0
For the Model layout and the last named layout made current, the
display list is saved to memory and regenerations are suppressed
1
when you switch between layouts. For all other layouts, regenera-
tions still occur when you switch to that layout.
The drawing is regenerated the first time you switch to each layout.
For the remainder of the drawing session, the display list is saved
2
to memory and regenerations are suppressed when you switch to
those layouts
The performance gain achieved by changing the LAYOUTREGENCTL setting
is dependent on several factors, including the drawing size and type, the
objects contained in the drawing, the amount of available memory, and the
effect of other open drawings or applications. When LAYOUTREGENCTL is
set to 1 or 2, the amount of additional memory used is the size of the Model
layout's display list multiplied by the number of viewports in each layout for
which the display list is saved.
1350 | Chapter 4 System Variables
If LAYOUTREGENCTL is set to 1 or 2 and performance seems slow in general
or when you switch between layouts for which the display list is saved, consider
changing to a setting of 0 or 1 to find the optimal balance for your work
environment.
Regardless of the LAYOUTREGENCTL setting, if you redefine a block or undo
a layout switch, the drawing is regenerated the first time you switch to any
layout that contains saved viewports.

IntegerType:
DrawingSaved in:
2Initial value:
When this system variable is off, exterior daylight is turned off when
photometric lighting is enabled (LIGHTINGUNITS (page 1352) system variable
is set to 1 or 2). When on, the exposure control algorithm in the rendering
acts as if there is an extremely bright light source in the scene. Therefore, the
default setting of Auto is tied directly to the sun setting. Under special
circumstances, it may be desirable to manually set this variable due to
extremely bright artificial light sources or, conversely, due to a sun-lit scene
that it is illuminated only by a small amount of directly visible sunlight.

MLEADERSCALE
Sets the overall scale factor applied to multileader objects.
RealType:
DrawingSaved in:
1.0000Initial value:
Use DIMSCALE (page 1239) to scale leader objects created with the LEADER
(page 567) command.
A reasonable default value is computed based on the scaling between
the current model space viewport and paper space. If you are in
0.0
paper space or model space and not using the paper space feature,
the scale factor is 1.0.
A scale factor is computed that leads text sizes, arrowhead sizes,
and other scaled distances to plot at their face values.
>0
MLEADERSCALE does not affect measured lengths, coordinates, or angles.
When MLEADERSCALE is set to 0, and the current multileader style is not
annotative, the overall multileader scale of multileader objects created in paper
space viewports is determined by the viewport scale. When the current
multileader style is annotative, the MLEADERSCALE value is set to 0. Changes
to the MLEADERSCALE value are ignored and the value is reset to 0.

Zooms the drawing to the extents of the multiline text object's
bounding box when the text in the In-Place Text Editor is difficult
0 or 1
to read (very small or large, or is rotated). The displayed text does
not represent the text object's final size and position.
If the text object is rotated, the drawing view is temporarily rotated
to match the orientation of the text object while it is being edited.
Smooth view transitions are used when the drawing view is zoomed
or rotated.
The text within the In-Place Text Editor is displayed at its actual size
and position. The display of the drawing is not zoomed or rotated,
which might make it difficult to edit very small or large text objects.

The value determines where the eye point clipping occurs as a percentage.
Values can range between 0.01 and 10.0. If you select a small value, the z-values
of objects will be compressed at the target view and beyond. If you select a
value such as 0.5%, the clipping will appear very close to the eyepoint of the
view. In some extreme cases it might be appropriate to use 0.1%, but it is
recommended to change the setting to a higher value such as 5%.

were created. Scaled by the global LTSCALE (page 593) factor.
0
Viewport scaling governs linetype scaling. If TILEMODE (page 1464)
is set to 0, dash lengths are based on paper space drawing units,
1
even for objects in model space. In this mode, viewports can have
varying magnifications, yet display linetypes identically. For a specific
1408 | Chapter 4 System Variables
linetype, the dash lengths of a line in a viewport are the same as
the dash lengths of a line in paper space. You can still control the
dash lengths with LTSCALE
When you change PSLTSCALE or use a command such as ZOOM (page 1153)
with PSLTSCALE set to 1, objects in viewports are not automatically regenerated
with the new linetype scale. Use the REGEN (page 877) or REGENALL (page

TREEDEPTH
Specifies the maximum depth, that is, the number of times the tree-structured
spatial index can divide into branches.
IntegerType:
DrawingSaved in:
3020Initial value:
Suppresses the spatial index entirely, eliminating the performance
improvements it provides in working with large drawings. This set-
ting assures that objects are always processed in database order.
0
Turns on spatial indexing. An integer of up to five digits is valid. The
first three digits refer to model space, and the remaining two digits
refer to paper space.
>0
Treats model space objects as 2D (Z coordinates are ignored), as is
always the case with paper space objects. Such a setting is appropri-
<0
ate for 2D drawings and makes more efficient use of memory without
loss of performance
NOTE
You cannot use TREEDEPTH transparently.

Work with Layer and Spatial Indexes
TREEMAX
Limits memory consumption during drawing regeneration by limiting the
number of nodes in the spatial index (oct-tree).
IntegerType:
RegistrySaved in:
10000000Initial value:
By imposing a fixed limit with TREEMAX, you can load drawings created on
systems with more memory than your system and with a larger TREEDEPTH
(page 1472) than your system can handle. These drawings, if left unchecked,
1472 | Chapter 4 System Variables
have an oct-tree large enough to eventually consume more memory than is
available to your computer. TREEMAX also provides a safeguard against
experimentation with inappropriately high TREEDEPTH (page 1472) values.
The initial default for TREEMAX is 10000000 (10 million), a value high enough
to effectively disable TREEMAX as a control for TREEDEPTH (page 1472). The
value to which you should set TREEMAX depends on your system's available
RAM. You get about 15,000 oct-tree nodes per megabyte of RAM.
If you want an oct-tree to use up to, but no more than, 2 megabytes of RAM,
set TREEMAX to 30000 (2 x 15,000). If the program runs out of memory
allocating oct-tree nodes, restart, set TREEMAX to a smaller number, and try
loading the drawing again.
The program might occasionally run into the limit you set with TREEMAX.
Follow the resulting prompt instructions. Your ability to increase TREEMAX
depends on your computer's available memory.

IntegerType:
DrawingSaved in:
0Initial value:
The UCSFOLLOW setting is saved separately for each viewport. If UCSFOLLOW
is on for a particular viewport, a plan view is generated in that viewport
whenever you change coordinate systems.
Once the new UCS has been established, you can use DVIEW (page 385), PLAN
(page 782), VIEW (page 1104), or VPOINT (page 1114) to change the view of the
drawing. It will change to a plan view again the next time you change
coordinate systems.
UCS does not affect the view0
Any UCS change causes a change to the plan view of the new UCS
in the current viewport
1
The setting of UCSFOLLOW is maintained separately for paper space and
model space and can be accessed in either, but the setting is ignored while in
paper space (it is always treated as if set to 0). Although you can define a
1478 | Chapter 4 System Variables
