progeCAD System Variables

progeCAD has hundreds of system variables that store the settings for various commands and functions. To see a complete listing of system variables, in the command bar, type setvar. Then type the system variable name to see the current value of that variable, or you can type ? to see the entire listing of system variables. Unless the variable is read-only, you can also change its value in the command bar. For variables that can be turned on or off, enter "1" or "On" to turn on the system variable, and enter "0" (zero) or "Off" to turn off the system variable.

Click a letter to go to that selection.
