Introduction

The Command Reference, a comprehensive guide to AutoCAD® commands, lists all AutoCAD 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.
The index for the Command Reference is at the end of Volume II.

Using AutoCAD Documentation

In addition to this Command Reference, several other resources are available to help you learn and use AutoCAD. The complete documentation set for AutoCAD 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 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 system variable governs whether you work in a dialog box or on the command line 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, no further action is required. For other commands, you must respond by providing additional information or actions in order to complete the command.
Using AutoCAD Documentation | 1
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 Options dialog box or with the SHORTCUTMENU system variable.
Starting Commands
You can start a command by doing one of the following:
Select the command from a menu, toolbar, 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 command:
Standard toolbar:
View menu: Pan Realtime
Shortcut menu: With no objects selected, right-click in the drawing area, and choose Pan.
Command line: pan (or 'pan for transparent use)
The availability of certain shortcut menus depends on the current setting of the SHORTCUTMENU 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 .
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 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/Aspect] <current>: on Resuming LINE command Specify first point:
2 | Chapter 1
In the Command Reference, the command access sections identify commands that you can use transparently.
Suppressing Dialog Boxes
Many commands provide both command line and dialog box interfaces. In most cases, when both a command line and dialog box interface are available, the command line version is preceded with a hyphen character. For example, the command line version of GROUP is -GROUP.
You can also control the display of file dialog boxes through the FILEDIA system variable. See appendix B, “System Variables”.
Responding to Prompts
If a command does not immediately execute, AutoCAD either displays a dialog box or displays prompts on the command line requesting more information. Command line 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 determines default 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 line prompts begin with the wordenter, select, or specify. These words indicate how you can respond to the prompt.
Terminology in command line prompts

Using This Reference | 3
Selecting Options on the Command Line
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 on the command line 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 on the Command Line
Some prompts ask you to enter data, rather than (or as an alternative to) choosing an option. To do so, enter the text on the command line and press ENTER or SPACEBAR . However, be aware that when the command line prompt requests an object name, SPACEBAR inserts a space on the command line 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 example, the POLYGON 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 on the Command Line
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 guides and other AutoCAD commands and system variables related to the current command.

Typographical Conventions

To orient you to AutoCAD features as they appear on the screen, specific terms are set in typefaces that distinguish them from the body text. Throughout AutoCAD documentation, the following conventions are used.

Rotation Angle
length
Rotates the box about the first corner specified. If you enter 0, the box remains orthogonal to the current X and Y axes.
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.
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 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.
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.

3DCONFIG

22 | Chapter 2
Provides a command-line interface to the 3D graphics system’s configuration settings
If you enter 3dconfig at the Command prompt, the following prompt is displayed on the command line:
Enter option: [Adaptive Degradation/Dynamic Tesselation/Render Options/Geometry/Acceleration/Exit] <Adaptive degradation>: Enter the
configuration you want to change or press ENTER to change adaptive degradation settings.
You will stay in the 3DCONFIG command until you enter eXit or press ESC.
Adaptive Degradation
Specifies the display options to which the view can degrade to maintain the speed of the view manipulation. For example, if a large drawing is currently Gouraud shaded, you can select Wireframe to allow the drawing to degrade to a wireframe representation of the view.
You can turn on one or more than one of the available options. If more than one option is turned on, the display changes to the most detailed option first and then degrades until it reaches the least detailed option.
Configure: Adaptive Degradation Enter mode [ON/OFF] <ON>: Specify whether you want adaptive degradation turned
on or off
If Adaptive Degradation is turned on, you can specify the type. If no type is specified, then no degradation will occur.
Current display options: Wireframe Bounding Box Enter option [Flat shaded/Wireframe/Bounding box/Maintain speed fps/eXit] <Flat shaded>: Specify the type of adaptive degradation you want to use Configure: Flat shaded Enter mode [ON/OFF] <OFF>: Specify whether you want flat-shaded display turned

Configure: Bounding box Enter mode [ON/OFF] <OFF>: S pecify whether you want bounding box display
turned on or off
Configure: Maintain speed fps Enter speed <5>: Enter a value between 1 and 60 to adjust the frame rate
Flat Shaded
Specifies that the display can change to flat shaded.
Adjust Clipping Planes Window | 23
Wireframe
Specifies that the display can change to wireframe. This uses less of the system resources and allows the drawing to move at a faster speed.
Bounding Box
Specifies that the display can change to a bounding box. A box is displayed in place of each object in your view. This choice requires the least amount of system resources.
Maintain Speed FPS
Specifies the display speed in frames per second. The drawing degrades to maintain the specified speed.
Dynamic Tesselation
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.
Configure: Dynamic tessellation Enter mode [ON/OFF] <ON>: Specify whether you want dynamic tessellation turned
on or off
If Dynamic Tessellation is turned on, you can specify the number of surface tessellations, curve tessellations, or tessellations to cache.
Configure: Dynamic tessellation Enter option [Surface tessellation/Curve tessellation/Tessellations to cache/eXit] <Surface tessellations>: Specify the type of dynamic tessellation you want to use Configure: Surface tessellation Enter tolerance <88>: Enter a value between 0 and 100 Configure: Curve tessellation Enter tolerance <88>: Enter a value between 0 and 100 Configure: Tessellations to cache Enter number of tessellations to cache <3>: Enter a value between 1 and 10
Surface Tessellation
Determines the amount of detail for surfaces in your drawing. The lower numbers provide less detail; the higher numbers provide more detail but use more tessellation lines and more memory.
Curve Tessellation
Determines the amount of detail for curves in your drawing. The lower numbers provide less detail; the higher numbers provide more detail but use more tessellation lines and more memory.
24 | Chapter 2
Number of Tessellations to Cache
Configures your system according to memory and performance requirements. A cache is a special memory subsystem that stores frequently accessed information. The 3D cache always stores at least one tessellation.
When the number of tessellations to cache is set to 1, the tessellation for all viewports is the same and may cause some objects in the drawing to be regenerated as you zoom in and out.
Setting the number of tessellations to cache to 2 or more is useful when you have more than one viewport with different views. Increasing the number requires more memory.
Render Options
Makes settings available for enhancing the display of lights, materials, textures, and transparency in 3D views. This includes objects in the 3D Orbit view and objects shaded using the SHADEMODE command.
Configure: Render options Enter mode [ON/OFF] <ON>: Specify whether you want to turn on render options Configure: Render options Enter option [Lights/Materials/Backgrounds/eXit] <Lights>: Specify whether you
want to configure lights, materials, or backgrounds
Configure: Lights Enter mode [ON/OFF] <ON>: Specify whether you want lights turned on or off Configure: Materials Enter mode [ON/OFF] <ON>: Specify whether you want materials turned on or off Configure: Backgrounds Enter mode [ON/OFF] <ON>: Specify whether you want backgrounds turned on or
off
If Render Options is turned on, you can specify if you want lights, materials, and backgrounds turned on or off.
Lights
In 3D views, illuminates objects and attached materials by lights that were defined with the LIGHT command. If this option is not selected, or if the LIGHT command has not been used for the drawing, then the default lighting for 3D views is used.
Materials
In 3D views, displays materials for objects that have materials that were attached using the RMAT command. If the object has no attached material, the default global material is used. If this option is not selected, or if the RMAT command has not been used in the drawing, then no materials are displayed.
Adjust Clipping Planes Window | 25
Backgrounds
Specifies that backgrounds will be displayed in 3D views while navigating and editing.
Configure: Textures Enter mode [ON/OFF] <ON>: Specify whether you want textures turned on or off Configure: Transparency Enter mode [Low/Medium/High] <Low>: Select a transparency level
If Materials is turned on, you can also configure textures and transparency.
Enable Textures
In 3D views, shows textures attached to objects using the RMAT and SETUV commands. Materials must also be turned on for textures to be visible.
Transparency
Adjusts the transparency quality to improve image quality, but at the expense of redraw time. At the low-quality setting, a screen-door effect achieves transparency without sacrificing speed. At the medium-quality setting, blending improves image quality. At the high-quality setting, blending and extra processing produce an image free of visual artifacts, but at the cost of drawing speed. Materials must also be turned on for transparency to be visible.
Geometry
Determines how to display isolines in 3D and whether to display back faces in 3D.
Configure: Geometry Enter option [Isolines on top/Discard backfaces] <Isolines on top>: Specify an
option to configure
Configure: Isolines on top Enter mode [ON/OFF] <ON>: Specify whether you want isolines on top Configure: Discard backfaces Enter mode [ON/OFF] <ON>: Specify whether you want back faces to be discarded
Isolines on Top
Displays isolines for front and back faces in all shade modes except Hidden. Isolines for the back faces are displayed on top of the shading for the objects in 3D. Turning this option off hides the isolines for the back faces.
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
26 | Chapter 2
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.
Acceleration
Specifies whether you want to use software or hardware acceleration in 3D.
Configure: Acceleration Enter option [Hardware/Software/eXit] <Hardware>: Specify whether you want to
configure hardware or software
Configure: Hardware Enter option [Driver name/Geometry acceleration/Antialias lines/eXit] <Driver name>: Specify an option to configure Available drivers: wopengl8.hdi Enter driver name <wopengl8.hdi>: Enter a driver name Configure: Geometry acceleration Enter mode [ON/OFF] <ON>: Specify whether you want geometry acceleration
turned on or off
Configure: Antialias lines Enter mode [ON/OFF] <ON>: Specify whether you want anti-alias lines turned on
or off
If you select Hardware, you can also specify whether geometry acceleration and anti-alias lines are turned on or off.
Hardware
Specifies hardware acceleration. Select to use the hardware graphics card to perform most of the drawing tasks in 3D. This speeds up the drawing time.
When you select Hardware, the default driver is set to the wopengl8.hdi driver that is included with the program.
If you select the Driver Name option, 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.
Software

A polygon mesh is defined by a matrix, the size of which is determined by M and N size values. M times N equals the number of vertices that you must specify.
Specify location for vertex (0, 0): Enter a 2D or 3D coordinate
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

closed mesh
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.

3DORBIT

Controls the interactive viewing of objects in 3D
View menu: 3D Orbit
Command line: 3dorbit, 3do
3DORBIT activates a 3D 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 Orbit view displays an arcball, which is a circle divided into four quadrants by smaller circles. When 3DORBIT is active, the target of the view stays stationary and the camera location, or point of view, moves around the target. The center of the arcball, not the center of the objects you’re viewing, is the target point.
NOTE You cannot edit objects while the 3DORBIT command is active.
Moving your cursor over different parts of the arcball changes the 3D Orbit Cursor Icons, indicating the direction in which the view rotates.
3D DWF Publish Dialog Box | 33
While the command is active, you can access additional 3DORBIT options from a shortcut menu by right-clicking in the drawing area, or choosing buttons on the 3D Orbit toolbar. See “3DOrbit Shortcut Menu” on page 35.

3D Orbit Cursor Icons

View rotation is determined by the placement and appearance of the cursor as follows:
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.
If you drag the cursor into the arcball it changes to a sphere encircled by two lines and the view moves freely. If you move the cursor back outside the arcball, you revert to 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.
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 were grabbing a sphere surrounding the objects and dragging it around the target point. You can drag horizontally, vertically, and diagonally using this method.
Vertical Ellipse
34 | Chapter 2
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.

3DOrbit Shortcut Menu

When the 3DORBIT command is active, you can change the view using one or more of the options on the 3D Orbit shortcut menu. To access the 3D Orbit shortcut menu, right-click in the 3D Orbit view.

3DOrbit Shortcut Menu | 35
Compass
Draws a 3D sphere within the arcball composed of three lines representing the X, Y, and Z axes.
Continuous Orbit
Changes the cursor to a sphere with two continuous lines encircling it and enables you to set the objects into continuous motion. See 3DCORBIT.
Flat Shaded
Shades the objects in the 3D Orbit view between the polygon faces. This gives the objects a faceted, less smooth appearance.
Flat Shaded, Edges On
Combines the Flat Shaded and Wireframe options. The objects are flat shaded with the wireframe showing.
Front Clipping On
Turns the front clipping plane on or off. A check mark in front of this option indicates that the front clipping plane is on and you can see the results of moving the line that adjusts the front clipping plane. See 3DCLIP.
Gouraud Shaded
Shades the objects in the 3D Orbit view and smooths the edges between polygon faces. This gives the objects a smoother, more realistic appearance.
Gouraud Shaded, Edges On
Combines the Gouraud Shaded and Wireframe options. The objects are Gouraud Shaded with the wireframe showing.
Grid
Displays a two-dimensional array of lines similar to graph paper. This grid is oriented along the X and Y axes.
Before starting 3DORBIT, you can use the GRID command to set system variables that control the grid display. The number of major grid lines corresponds to the value you set using the Grid Spacing option of the GRID command, which is stored in the GRIDUNIT system variable. Ten horizontal lines and ten vertical lines are drawn between the major lines.
Hidden
Displays the objects in the 3D Orbit view as wireframes with the lines representing the back faces hidden.
36 | Chapter 2
Orbit Maintains Z
Keeps the Z axis in its current orientation when dragging horizontally within the arcball circle, or when dragging from the small circles on the left or right side of the arcball. When using 3D Orbit, use this option to keep the object from tumbling end-over-end. This option is useful for changing the view of such drawings as buildings, cars, and maps. This setting is saved with the user profile.
Orbit Uses AutoTarget
Keeps the target point on the objects you are viewing rather than on the center of the viewport. This feature is turned on by default.
Parallel
Displays objects so that two parallel lines in a drawing never converge at a single point. The shapes in your drawing always remain the same and do not appear distorted when they are closer.
Perspective
Displays objects in perspective so that all parallel lines converge at one point. Objects appear to recede into the distance, and parts of the objects appear larger and closer to you. The shapes are somewhat distorted when the object is very close. This view correlates more closely to what your eye sees.
Swivel Camera
Changes the cursor to an arched arrow and simulates the effect of turning the camera. See 3DSWIVEL.
UCS Icon
Displays a shaded 3D UCS icon. Each axis is labeled X, Y, or Z. The X axis is red, the Y axis is green, and the Z axis is blue.

42 | Chapter 2
Multiple Material Objects
3D Studio assigns materials by face, element, or object. AutoCAD assigns materials by object only. When AutoCAD encounters a 3D Studio object assigned multiple materials, AutoCAD must find a way to handle the assignment.
Always Prompt
Displays the Material Assignment Alert dialog box for each object with multiple materials. The dialog box displays the name of the object. The options you select determine how 3DSIN handles the assignment. The options are as follows:
Split by Material
Splits all objects with multiple materials into multiple objects, one for each material. This preserves the material assignments that were made in the 3D Studio file. It also increases the complexity of the drawing geometry.
Assign First Material
Assigns the first material assigned to each multiple-material object to the entire object. See the 3D Studio documentation for an explanation of how the first-assigned material is determined.
Don’t Assign a Material
Assigns no material to each multiple-material object. This option loses all material assignment information but preserves the 3D Studio geometry. The object reverts to the AutoCAD default material.

3DSWIVEL

Starts the interactive 3D view and simulates the effect of turning the camera
3D Orbit toolbar:
Shortcut menu: Start the 3DORBIT command, right-click in the drawing area,
and choose More Swivel Camera.
3D Studio File Export Options Dialog Box | 45
Command line: 3dswivel
3DSWIVEL changes the cursor to an arched arrow and simulates the effect of turning a camera on a tripod. This command changes the target of the view. For example, if you were pointing a camera at an object and then turned the camera to the right, the object would move to the left in your viewing area. Or, if you pointed the camera up, the objects would move down in your viewing area. Swivel simulates this motion by using the cursor as the camera’s viewfinder.

3DZOOM

Starts the interactive 3D view so you can zoom in and out on the view
3D Orbit toolbar:
Shortcut menu: Start the 3DORBIT command, right-click in the drawing area, and choose Zoom.
Command line: 3dzoom
3DZOOM simulates the effect of a camera’s zoom lens. It makes objects appear closer and farther away but does not change the position of the camera. Zooming in magnifies the image. This also exaggerates the perspective with which you view the objects if you’re using perspective projection. It may slightly distort the shape of some objects.
Zoom changes the cursor to a magnifying glass with plus (+) and minus (–) signs. Clicking and dragging the cursor vertically toward the top of the screen zooms in on the image, making the objects appear larger or closer. Clicking and dragging the cursor vertically toward the bottom of the screen zooms out and makes the object appear smaller or farther away.

target box target box
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.

APERTURE

Controls the size of the object snap target box
Command line: aperture (or 'aperture for transparent use)
Object snap target height (1–50 pixels) <current>: Enter a value (1–50) or press ENTER
60 | Chapter 3
Object snap applies only to objects inside or crossing the object snap target box. The APBOX system variable controls whether the object snap target box is displayed. The number of pixels you enter using APERTURE controls the size of the object snap box. The higher the number, the larger the target box. You can also change this setting in the Options dialog box, Drafting tab.
APERTURE controls the object snap target box, not the pickbox displayed at the Select Objects prompt. The object selection pickbox is controlled by the PICKBOX system variable.

APPLOAD

Loads and unloads applications and defines which applications to load at startup
Tools menu: Load Application
Command line: appload
The Load/Unload Applications Dialog Box.

Load/Unload Applications Dialog Box

Tools menu: Load Application
Command line: appload
Loads and unloads applications and specifies applications to be loaded at startup.
Load/Unload Applications Dialog Box | 61
The options at the top of this dialog box are derived from the Standard File Selection Dialog Boxes. Following are descriptions of the additional options provided by the Load/Unload Applications dialog box:
Add to History
Adds any applications that you load to the history list.
You may prefer to clear this option when loading applications with the AutoCAD web browser, because these applications are unavailable once the cache for the application’s temporary location is emptied.
Contents
Displays the Startup Suite Dialog Box. You can also add files to the Startup Suite by clicking the Startup Suite icon or by right-clicking an application on the History List tab and clicking Add to Startup Suite on the shortcut menu.
History List
Displays an alphabetical list (by file name) of applications that you previously loaded with Add To History selected. You can drag files into this list from the files list, or from any application with dragging capabilities, such as Windows Explorer. If Add To History is not selected when you drag files into this list, the dragged files are loaded but not added to the history list.
You can load and remove applications from this list, but to unload applications, you must use the Loaded Applications tab. See the Load, Unload, and Remove options.
Load
Loads or reloads the applications that are currently selected either in the files list or on the History List tab. Load is unavailable until you select a file that you can load. ObjectARX, VBA, and DBX applications are loaded immediately, but LSP, VLX, and FAS applications are queued and then loaded when you close the Load/Unload Applications dialog box.
If you select a file that is already loaded, Load reloads the application when applicable. You cannot reload ObjectARX applications. In this case, you must first unload the ObjectARX application and then load it again. The Load option is also available from a shortcut menu by right-clicking a file on the History List tab.
Loaded Applications
Displays an alphabetical list (by file name) of currently loaded applications. LISP routines are displayed in this list only if you loaded them in the
62 | Chapter 3
Load/Unload Applications dialog box. You can drag files into this list from the files list or from any application with dragging capabilities, such as Microsoft® Windows® Explorer.
If you use the AutoCAD web browser to load an application, the web browser downloads the application to a temporary location on your machine. This is the location from which AutoCAD loads the application, as displayed in this list.
You can also unload certain applications from this list. See the Unload option for details. Files that you cannot unload are not available for selection.
Startup Suite
Contains a list of applications that are loaded each time you start AutoCAD. You can drag application files from the files list, or from any application with dragging capabilities such as Windows Explorer, into the Startup Suite area to add them to the Startup Suite.
You cannot add applications that you load with the AutoCAD web browser to the Startup Suite.
Status Line
Displays messages that indicate the status of loading and unloading operations.
Unload/Remove
Unloads the selected applications or removes them from the History List. Unload is available only when a file is selected on the Loaded Applications tab. Remove is available only when you select a file on the History List tab.
LISP applications cannot be unloaded, nor can ObjectARX applications that are not registered for unloading.
Note that Remove does not unload the selected application. The Remove option is also available from a shortcut menu by right-clicking an application on the History List tab.
