Hi Thomas, thanks for your quick reply. By a surface mesh I mean a mesh of the surface of the shape (which is actually a volume with some holes). The simple_mesh.py example seems to be what I need. I could extend the example to get the coordinates of the vertices of the triangulation. Where can I find information about the internals of the BRepMesh_Mesh function?

If your need it to import a STEP file, convert it to a TopoDS_Shape and then mesh this shape in order to get vertices/vertex index/faces, it is possible with blending the SETPImport samples and the src/examples/Level1/Mesh/simple_mesh.py example. You should have a look at the latter. Please feel free to post here a sample STEP file as well as the python source code.
