Questions tagged [autocad]

Questions specific to AutoCAD, as opposed to general computer-aided drafting and design issues.

This tag should be used to categorize questions that pertain specifically to Autodesk's AutoCAD and (preferably) no other CAD tool.

Questions about using CAD tools in general, or where the asker's use of AutoCAD is entirely coincidental to the problem at hand, should use the more general computer-aided-design tag. In some cases, both of these tags can be applied to the same question.
