摘　　要：特征提取技术对于信息的共享与CAD/CAM的集成具有重要意义。为了合理地提取CAD系统中的设计信息,给出了组合特征的概念,在此基础上讨论了通过特征映射提取组合特征的方法,介绍了Pro/E平台下的组合特征提取的开发过程。最终的提取结果验证了提取方案的合理性。Feature extraction technology has great significance for information sharing and integration of CAD and CAM. The notion of compounded feature was defined for extracting design information in CAD systems reasonably. On this basis, the method to ex- tract compounded feature by feature mapping was discussed, the development process of compounded feature extraction in Pro/E platform was introduced. Finally, the validity of the scheme was confirmed by example.
