after import from iges some meshes are double

I experienced much difficulties after exporting the ceiling detail pictured here that hopefully is related to how I set up the IGES and SAT exports from MOI for use in VectorWorks (VW). It could be VW and the way it handles IGES and SAT files.

After successfully importing the IGES and SAT files into VW, the objective is to convert them to 2D isometrics, which allows modifications. Also, the workflow is faster since rendering is no longer necessary. In VW, converting to 2D is done with Hidden Line Rendering and then selecting Convert Copy to Polygons.

The ceiling MOI file is 4.5 mb, the exported IGES and SAT files are 6.9 and 8.7, and after opening in VW, 4.3 and 6.2.

Now, when I convert to 2D, these files have a growth spurt - 396.5 mb and 495.6 mb! (Think "King Kong".)

Is there anything I can do on the MOI end to keep this from occurring? (VW, right?)

Thanks.
