摘要
分析了现有的异构CAD系统之间数据交换存在的问题。提出了基于特征映射的数据交换方法,建立中性建模命令集,其参数是异构CAD系统建模命令的并集,以该中性建模命令集为中介,实现异构CAD系统建模命令的映射,从而达到异构系统协同的目的,保证了异构CAD系统设计和加工模型的一致,缩短了产品的开发周期。最后给出了一个从Pro/E系统转换到UG系统的简单实例,验证了方法的可行性。
Analyze the problem of data exchange technology in existing heterogeneous CAD system.Put forward a new data exchange technology which based on feature-mapping, found a middle-modeling-order, its parameter is the aggregate of the heterogeneous CAD system. Through the agency of middle-modeling-order, carry out the feature-mapping in heterogeneous CAD system, can ensure the consistent of design and model in heterogeneous CAD system, and shorten the period of product exploitation. Finally, an instance which changed from Pro/E to UG is provided, this validate the feasibility of the method.
