Appendix D. System Variables
AutoCAD stores the values for its operating environment and some of its commands in system variables. System variables control how the commands work. They also set default colors, sizes, and values. They store information about the drawing and the software configuration. Some system variables can be changed by the user; others are read-only.
To see a list of all system variables and their current settings, type SETVAR at the command line, type “?”, and then “*”.
Use AutoCAD’s Help feature for additional information about system variables and their options.
