dxf/dwg issue

I am trying to import a dxf or dwg into a solid model so Ican cut out a design. This seemed to be an easy thing to do in thebeginning and I follow the Solidworks tutorial, but I can not getthe dwg/dxf to define. It seems that even the simpler items Iimport stall my computer. I can import a square, and that is aboutit. Is there a trick I can try, or a setting to check? I have triedusing dxf's and dwg's and neither work.

The guy next to me using AutoCad has no problem doing this, so I amnot looking good on this one.SolidworksImport export
