After checking out all the other StackExchange sites, CAD questions do not seem to fit into any category except maybe superuser. In the FAQ, superuser is described as encompassing general software or hardware troubleshooting, which is the closest fit to an application such as AutoCAD.
Mainly I'm asking this question because I searched for "autocad" and "cad" tags, of which there are very few, and neither have a tag wiki.
