System Variables

AutoCADĀ® stores the values for its operating environment and some of its commands in system variables. You can examine any system variable and change any writable system variable directly at the Command prompt by entering the system variable name or by using the SETVAR command or the AutoLISPĀ® getvar and setvar functions. Many system variables are also accessible through dialog box options.

To access a list of system variables, on the Contents tab of the Help window, click the + sign next to System Variables.
