摘　　要：在实体建模中,奇异特征的存在阻碍了基于特征的数据交换的顺利进行。针对该问题,提出一种在特征交换框架下基于几何操作的奇异特征交换方法,通过将奇异特征转化为一组与之等价的几何操作实现奇异特征的交换。实验结果表明,该方法能有效解决异构CAD系统间奇异特征的交换问题。In solid modeling, due to the existence of singular features, feature based data exchange is blocked. Aiming at this problem, an exchange approach for singular features based on geometry operations is presented under the feature exchange framework. It realizes singular feature exchange by transforming it into a group of geometry operations, which are equal to the singular feature. Experimental results show that the method can solve the problem of singular feature exchange among heterogeneous CAD systems effectively.
