摘　　要：针对异构CAD系统间交换数据重构问题,提出基于引用拓扑实体方法,将建模历史节点引用永久拓扑命名转化可准确表征的中间拓扑实体,利用中间拓扑数据对当前重构节点实体进行完整记录和精确表征,以在目标CAD系统中实现该中间引用拓扑实体到永久拓扑命名的映射,达到异构CAD系统间数据模型重构的需求。最后,所提方法已在国内某国产工业软件中得到成功的测试案例,证明了该理论的可行性。Aiming at the problem of exchanging data reconstruction between heterogeneous CAD systems,a method based on reference topological entity was proposed to transform the reference permanently name topological entity of the modeling history node into an intermediate topological entity that could be accurately characterized.The current reconstructed node entity was completely recorded and accurately characterized using the intermediate topological data.Then the mapping of the intermediate reference topological entity to the permanent topological name was realized in the target CAD system.So the purpose of data model reconfiguration between different heterogeneous CAD systems was achieved.Finally,the proposed method was successfully tested in a domestic industrial software,the feasibility of the theory was demonstrated.
