Hi Thomas, Dave,
This discussion needs some precision: the SMESH* modules are there to create
FEM meshes.
I think what Dave is looking for is meshes the represent the BREP geometry,
right?
Here's a snippet how you can access the triangulation of a face.
Note that triangulation are build in OCC on a per-face basis.
-jelle
T = BRep_Tool().Triangulation(face, face.Location()).GetObject()
nodes, uv_nodes, triangles = T.Nodes(), T.UVNodes(), T.Triangles()
print 'Number of Triangles:', triangles.Length()
