Summary: Spaceclaim STEP converter.

Initial Comment:
There is a CAD software package called Spaceclaim that has a STEP to BRL-CAD converter.  It converts objects to BOTs in BRL-CAD.  Will the BRL-CAD step-g converter create primitives when converting or will it be BOTs as well?

Message:
The step-g importer aims to preserve the original geometry format as best
possible.  It is specifically written to bring in NURBS boundary
representation geometry common in other commercial CAD systems.  So, no, it
generally won't bring an object in as a BoT unless it's a mesh format
geometry to begin with (in which case it could come in as a BoT or a
polygonal NURBS mesh, but isn't presently implemented to do either).

(for what it's worth, BoTs are also "primitives", they're just an explicit
representation primitive)
