Webwith boundary is not a manifold with boundary. On the other hand, the Cartesian product of manifolds only one of which has boundary, is a manifold with boundary (why?) … WebBoundary representation (B-Rep) CAD models represent a volume via the formal definition of its surface boundary. This representation is commonly applied in parametric CAD formats including the STEP format ( Bhandarkar et al., 2000 ). The B-Rep protocol applies a quilt of surface patches to enclose the volume of interest.
