When I try to extrude dxf files that I have imported from adobe illustrator, they extrude but there is also a rectangular panel attached to the extruded shape

Also it may be better to save as a PDF or AI v8 file to move over, it could be possible that using DXF export out from Illustrator would convert things to all line segments instead of keeping the actual curves intact.
