I have had a periodically recurring problem when importing .dxf's or .dwg's from AutoCAD (any version).
I will import an AutoCAD drawing (.dxf or .dwg ) into a new VW drawing. This seems to work fine. I will then try to copy elements from the imported drawing to an existing drawing. When pasted, these copied objects are visible but untouchable (can't grab 'em or select 'em), and when grouped, they disappear completely. Scary.
I have tried having the AutoCAD drawings exported as previous versions, exploded to lines...everything I could think of. I have also ungrouped everything, converted to lines, and purged all in an effort to make it work. Unsuccessful.
In the Architectural (or any) building design field, interaction with AutoCAD is a necessary (and unavoidable) evil. This must work! Don't know where the problem lies, but I suspect misunderstood ACAD objects...
Anyone experienced this? Ideas...?
My config. is as follows:
G4/400, 192ram, OS 9.0.4, VW 8.5.2
