Can anyone help me convert a Solidworks file to an AutoCAD file?  I contract work for the DOD and I have a 3D building that is in AutoCAD (it needs to stay an AutoCAD file, I can't convert it to another software).  My contractor that designs my furniture and office equipment does so in Solidworks.  I need to "import" his files into my drawing so that I can render a final image.  I downloaded the IGES and STL import from SYCODE.  The STL import worked however, the file isn't really usable.  I imported a desk phone, a small simple file, and it coverted it to 90,000 faces.  It's not edittable and I can't even move it because the system freezes since there's so many faces.  I tried importing a desk and AutoCAD froze and shut down.  I have plenty of space on my computer so that's not the issue.  Does anyone have any suggestions or know how I can import a Solidworks file without it creating thousands of faces?  The mesh option didn't seem to work either.

try using .stp or .step to import your data.
Im using inventor 2010 and i know that if i bring in an iges is looks like sh*t, is all clear and made up of thousands of faces i cant do anything with. maybe same issue?

Ask your SW person to save as dwg 3d.

Or try stp files, they generlly work better than igs
