I use Open Inventor, not Performer, and I have the same problem. I have
been modeling in Infini-D on the Mac, saving the model as a DXF file, and
using DxfToIv. Often I am missing one or more faces on the Inventor model.
I haven't checked, but they could be backwards and so they aren't drawn.
I have only looked at them with ivview.
