The other advice (that Mark Toce with DC LLC imparted to me) is to never, NEVER, **EVER** import an Acad DWG into an AEC file that you're working on. Import it into a new drawing, then you can either xref it in (as Roger suggested) or then select what you need and cut-n-paste it into the AEC file you are working on.
