component decomposition.Then we create the simplest possible surface geometry for each face loop in the interpretations and compare the solutions geometrically to output surface models representing simpler shapes.Similarly,we generate interpretations representing an open surface that is homeomorphic to a disc.Our method can be applied to construct a CAD system that supports multiple
