Thank you for your support. You can get vertex coords/normals/vertex indices/faces with the help of the OCC.Msh.Mesh.py module. Here is an example that meshes a box, and prints the result. HTH Thomas ======= from OCC.BRepPrimAPI import BRepPrimAPI_MakeBox from OCC.MSH.Mesh import * box_shape = BRepPrimAPI_MakeBox(1,1,1).Shape() init_time = time.time() a_mesh = QuickTriangleMesh() a_mesh.set_shape(box_shape) a_mesh.set_precision(0.3) a_mesh.compute() print 'Number of triangles: %i'%a_mesh.get_nb_faces() print 'Number of vertices: %i'%a_mesh.get_nb_nodes() #a_mesh.build_lists_shared_vertices() print 'All done in %f seconds.'%(time.time()-init_time) # print "#################" print a_mesh.get_vertices() print "##############" print a_mesh.get_normals() print "################" print a_mesh.get_faces()
