An Approach of Constructing Neutral Modeling Command Set of Synchronized Collaborative Design upon Heterogeneous CAD Systems

The synchronized collaborative design within heterogeneous CAD systems becomes a significant challenge because of the great difference between the modeling operations and underground data structures of different systems. In order to enable it, this paper researches an approach to constructing the neutral modeling command set, an important part of synchronized collaborative design systems, to build the mapping of operations among different CAD systems. A prototype is developed based on the neutral modeling command set to verify the feasibility of the proposed approach.
