I have been trying to import and open an autocad .dwg 3D file of furniture.  I can open it without issue on the Autocad site using their viewer feature so I know the dwg is not corrupted.  When I import the dwg into Solid Works I get a weird blue wireframe of the item.  The wireframe is 3D but not usable.  Do I need to adjust some import settings or import it as a different file type than I usually do- or do I need to convert the .dwg into another file type and then into Solidworks?  Thank you.
