I use Solidworks at work and at home for graphics work and do the same thing. Solidworks/IGES/MOI/OBJ to render. It would be sweet to have leave out the solidworks but sometimes you need to chop up the assembly into smaller bites for MOI to handle.

Speaking of that it would be nice during import to use multi-core support. I have noticed when bringing in large assemblies that only one of my cores is taking an ass beating. Is multi core use during import possible, I have seven others that sit around and kick rocks. I have not check but during meshing is that a single core process as well?
