Examples

>>> from compas.datastructures import Mesh
>>> mesh = Mesh.from_polyhedron(6)
>>> expa = mesh_conway_expand(mesh)
>>> expa.number_of_vertices() == 2 * mesh.number_of_edges()
True
>>> expa.number_of_edges() == 4 * mesh.number_of_edges()
True
>>> expa.number_of_faces() == mesh.number_of_vertices() + mesh.number_of_faces() + mesh.number_of_edges()
True
