This thread is probably the best place to continue the discussion for now
because the hard part will be figuring out how to do the IFC procedural
geometry with BRL-CAD. BRL-CAD already uses STEPcode for their STEP
importer. So the explicit geometry from IFC could be handled by STEPcode.
The implicit IFC geometry (procedural things like extrusions) will have
to be handled by the BRL-CAD procedural capabilities.
