System Variables R12 – R2009

“What do you want to store or retrieve today?”

AutoCAD Systems Variables is where AutoCAD does most of its storing of temporary and some permanent values. These values are related to commands and to control how the user interacts with the AutoCAD Environment. Some of these values are drawing parameters for commands like Offset distance, Circle radius and the Units in which are used to input values when drafting. Related Commands Setvar - Calls the System Variable command. Through the use of this command you can set a System Variables value or you can get a listing of all the current settings of all the System Variables. Command: Setvar Variable name or ?: ? Variable(s) to list <*>: * or AutoLISP Functions (setvar variable value) - Sets the value of a System Variable (getvar variable) - Gets the value of a System Variable Note: Read-only variables are denoted by the name of the system variable being in italic font.
