A method for reducing the complexity of a triangulated CAD model while preserving the topological properties and shape of the original model is disclosed. In operation, the system and method identifies a plurality of coplanar vertices in a CAD model, removes the coplanar vertices if they form a circle...http://www.google.fr/patents/US6744434?utm_source=gb-gplus-shareBrevet US6744434 - Cuts removal system for triangulated CAD Models
