CGM consists of a set of wrapper functions which translate function calls such that they access geometry in its native format. However, CGM also provides functionality not found in most modelers, like support for non-manifold topology, and alternative geometric representations, including mesh-based and facet-based geometry. CGM is designed to be extensible, so that applications can define application-specific behavior for geometry entities. CGM is also designed to be easily portable to other geometry modeling engines. Ports to Solid Works and Pro/Engineer are underway.
