Replicated collaborative solid modeling and naming problems

A method of multi-user interaction in replicated collaborative solid modeling (CSM) is proposed. New challenges and problems of name consistency are analyzed. A roadmap for name consistency is explored. The roadmap uses a distributed method to correspond topological entities across sites. A faceIndex structure is organized to enable overall corresponding among intervals of interaction steps. A priority point based method is presented to sort exact faceIndex of faces inside each step. The above methods are illustrated with a case study.
