Stores the default angle when rotating the UCS around one of its axes using the X, Y, or Z option of the UCS command. Its value must be entered as an angle in degrees (valid values are: 5, 10, 15, 18, 22.5, 30, 45, 90, 180).
Stores the name of the UCS that defines the origin and orientation of orthographic UCS settings. Valid values include any named UCS.
Controls whether dynamic UCS acquisition is active or not.
Generates a plan view whenever you change from one UCS to another. 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.
Displays the UCS icon for the current viewport or layout. This system variable has the same name as a command. Use the SETVAR command to access this system variable.
Stores the name of the current coordinate system for the current viewport in the current space. Returns a null string if the current UCS is unnamed.
Stores the origin point of the current coordinate system for the current viewport in the current space. This value is always stored as a world coordinate.
Determines whether the related orthographic UCS setting is restored automatically when an orthographic view is restored.
Determines whether the current UCS is saved with a named view.
Determines whether the UCS in viewports remains fixed or changes to reflect the UCS of the current viewport. The setting of this system variable is viewport specific.
Stores the X direction of the current UCS for the current viewport in the current space.
Stores the Y direction of the current UCS for the current viewport in the current space.
Indicates the state of the Auto, Control, and Group options of the UNDO command. The setting is stored as a bitcode using the sum of the following values:
Stores the number of marks placed in the UNDO control stream by the Mark option. The Mark and Back options are not available if a group is currently active.
Controls the display format for units. By default, the format for displaying measured values differs slightly from the format used for entering them. (You cannot include spaces when entering measured values.)
Controls updating of the thumbnail previews in the Sheet Set Manager. The setting is stored as a bitcode using the sum of the following values:
Provides storage and retrieval of integer values. There are five system variables: USERI1, USERI2, USERI3, USERI4, and USERI5.
Provides storage and retrieval of real numbers. There are five system variables: USERR1, USERR2, USERR3, USERR4, and USERR5.
Provides storage and retrieval of text string data. There are five system variables: USERS1, USERS2, USERS3, USERS4, and USERS5.
