AutoCAD has a number of system variables controlling all manner of options within the AutoCAD environment. Some variables act on a ‘per drawing’ basis whilst others affect the AutoCAD application itself. Today I’m going to run through a few of the common System-wide variables (i.e. those that affect the options within AutoCAD itself).
You can display a Dialog box showing the numerous system variables available and their current settings using the System Variable Editor Express Tool:
Generally most users will want to keep the system variables set to their default values but occasionally (particularly following a fatal crash) the variable may be left in an altered state and needs to be reset to a different value. The System Variable Editor can prove a useful resource to find out what the initial value of a variable would be and reset if required.
The following are just a few of the Registry variables that may need to be accessed and changed if the current value causes AutoCAD/AutoChart to not behave as expected.
