Controls whether the drawing is saved with visual fidelity
Stores the current automatic save file name.
Specifies the path to the directory for all automatic save files for the current session. You can also change the path on the Files tab in the Options dialog box.
Displays the file name and directory path of the most recently saved drawing.
Sets the automatic save interval, in minutes.
Stores the number of boxes in the screen menu area of the drawing area. If the screen menu is turned off, SCREENBOXES is zero. On platforms that permit the drawing area to be resized or the screen menu to be reconfigured during an editing session, the value of this variable might change during the editing session.
Indicates the state of the display. The setting is stored as a bitcode using the sum of the following values:
Stores current viewport size in pixels (X and Y).
Controls whether alternate scale representations are temporarily displayed in a dimmed state when an annotative object is selected
Controls the display of effects for selection areas. Selection areas are created by the Window, Crossing, WPolygon, and CPolygon options of SELECT.
Controls the transparency of the selection area during window and crossing selection. The valid range is 0 to 100. The lower the setting, the more transparent the area. A value of 100 makes the area opaque. The SELECTIONAREA system variable must be on.
Controls the display of selection previewing. Objects are highlighted when the pickbox cursor rolls over them. This selection previewing indicates that the object would be selected if you clicked. The setting is stored as a bitcode using the sum of the following values:
Controls which properties are selected for SETBYLAYER
Controls the shading of edges in rendering.
Sets the ratio of diffuse reflective light to ambient light. The ratio is a percentage of diffuse reflective light when SHADEDGE is set to 0 or 1.
Controls the location of an invisible ground plane used to display shadows. The value is a location on the current Z axis. The ground plane is invisible, but it casts and receives shadows. Objects that are located below the ground plane are shadowed by it. The ground plane is used when the VSSHADOWS system variable is set to display either full shadows or ground shadows.
Controls whether Default, Edit, and Command mode shortcut menus are available in the drawing area. The setting is stored as a bitcode using the sum of the following values:
Controls the Show History property for solids in a drawing.
Displays icons in the Layer Properties Manager to indicate whether layers are in use. Setting this system variable to Off improves performance in the Layer Properties Manager.
Sets a default shape name that must conform to symbol- naming conventions. If no default is set, it returns "". Enter a period (.) to set no default.
Controls whether a warning is presented when a file with an attached digital signature is opened. If the system variable is on and you open a file with a valid signature, the digital signature status is displayed. If the variable is off and you open a file, the digital signature status is displayed only if a signature is invalid. You can set the variable using the Display Digital Signature Information option on the Open and Save tab of the Options dialog box.
Sets the record increment for the SKETCH command.
Determines whether the SKETCH command generates lines or polylines.
Sets the snap and grid rotation angle for the current viewport. The angle you specify is relative to the current UCS.
Sets the snap and grid origin point for the current viewport relative to the current UCS.
Controls the isometric plane for the current viewport.
Turns the Snap mode on and off.
Sets the snap style for the current viewport.
Sets the type of snap for the current viewport.
Sets the snap spacing for the current viewport. If SNAPSTYL is set to 1, the X value of SNAPUNIT is adjusted automatically to accommodate the isometric snap.
Turns the solid validation on and off for the current session.
Controls the default History property setting for new and existing objects. When set to 1, composite solids retain a “history” of the original objects contained in the composite.
Controls the display of splines and spline-fit polylines.
Sets the number of line segments to be generated for each spline-fit polyline generated by the Spline option of the PEDIT command.
Sets the type of curve generated by the Spline option of the PEDIT command.
Displays the sheet set path and file name if a search for a sheet set is successful.
Controls whether the sheet set associated with a drawing is located and opened when the drawing is opened.
Controls the display behavior of the Sheet Set Manager when a drawing associated with a sheet is opened.
Controls the time interval between automatic refreshes of the status data in a sheet set.
Controls how the status data in a sheet set is refreshed.
Determines whether the Sheet Set Manager window is open or closed.
Specifies whether a user is notified of standards violations in the current drawing when a nonstandard object is created or modified.
Controls whether the Create New Drawing dialog box is displayed when a new drawing is started with NEW or QNEW. Also controls whether the Startup dialog box is displayed when the application is started.
Specifies the size of each step when in walk or fly mode, in drawing units. You can enter any real number from 1E-6 to 1E+6.
Specifies the number of steps taken per second when you are in walk or fly mode. You can enter any real number from 1 to 30.
Indicates whether the Sun Properties window is open or closed.
Controls whether the sun casts light in the current viewport.
Sets the number of tabulations to be generated for the RULESURF and TABSURF commands. Also sets the mesh density in the M direction for the REVSURF and EDGESURF commands.
Sets the mesh density in the N direction for the REVSURF and EDGESURF commands.
Controls the type of surface-fitting to be performed by the Smooth option of the PEDIT command.
Sets the surface density for PEDIT Smooth in the M direction and the U isolines density on surface objects. Valid values are 0 through 200. Meshes are always created with a minimum surface density of 2.
Sets the surface density for PEDIT Smooth in the N direction and the V isolines density on surface objects.. Valid values are 0 through 200. Meshes are always created with a minimum surface density of 2.
Indicates the system code page, which is determined by the operating system. To change the code page, see Help in your operating system.
