Collaborative design framework upon heterogeneous CAD systems
异构CAD系统协同构架研究

Aimed at the differences of operating instructions and data structure upon heterogeneous CAD systems,and based on the technology of semantic feature modeling,this paper proposed a kind of new architecture which could support the collaborative design of heterogeneous CAD systems.It solved the problem of "writing conflict" between heterogeneous CAD systems effectively by a kind of new scheduling policy,improved the efficiency of real-time response.The preliminary applications in the collaborative design between HUST-CAIDS and AutoCAD were introduced to prove the feasibility of the theories above.
