I am migrating from an older version to 7.4.0. My prior version code loads a TopoDS_Shape from STEP, performs BRepMesh_IncrementalMesh and then used STLMesh to iterate over triangles, mapping g_Pnts and implied edges into an adjacency graph.
I can understand how to do this mapping with a Poly_Triangulation object. However, I can't seem to find anywhere in the documentation how to get the Poly_Triangulation handle of the TopoDS_Shape to get the process started.
What am I missing?
