METHODS USED TO BODIES CONSTRUCTING

The main elements of the geometric model are bodies. C3D geometric kernel constructs bodies that fully or partially describe the surface of the modeled object. The body can be closed or non-closed. A closed body does not contain boundary edges. It describes the whole surface of the modeled object and the set of its internal points. A non-closed body contains boundary edges. It describes only a part of the surface of the modeled object. Many bodies have a simple form and are built on the basis of points, curves and surfaces.
