                                        defines a manifold body with all the necessary topology
                                        information like shells, faces, loops, edges and
                                        vertices.

                                        Trimmed surfaces (Type 144): The boundaries of these
                                        surfaces will be represented by Curve on a Parametric

                                        surfaces will be represented by Boundary Entity (Type 141).
                                        The boundary entity will refer to model space curves and
                                        surface parametric curves, with preference set to model
                                        space curves.
