For example, let's say that I've build a StepShape_FacetedBrep entity, and I want to let StepToTopoDS_Builder make a TopoDS_Shape out of it, so I can extract the triangles for a third party renderer - How do I actually do that? I need a Transfer_TransientProcess handle to construct the Builder, and if I just make on and pass it on to it's c'tor, attaching a mesh to the shape throws an exception.
I'm not actually reading STEP files, I'm dynamically creating StepShape's and I want to build the geometry automatically. I don't need to know about StepReader/Writer and all that, I just need to use the Builder to get my triangles. Any help on that?
