Thanks Michael,

Problem is, when I open up an iges file of a solid model, it's really a bunch of surfaces.

I thought the modeling in MoI was done in Solids++, a kernel similar to granite, parasolid or acis. That would allow a clean export of the solid model back into the CAD package for minor solids editing, and documentation. I lose too much solids intelligence, and gain file size bloat using iges.

Is the MoI modeling done in Solids++? I notice if I create a block, I can delete one of it's faces, something I could never do in one of the other packages.

Mike..
