摘要
特征造型是CAD技术的发展趋势之一，基于特征的设计在CAD/CAM中扮演了重要的角色。本文结合工程实际，探讨了特征的定义及分类方法，提出了支持特征设计的新型数据结构并研究了基于特征的造型操作方法 ——动态拓扑信息处理方法及特征管理模式。
Feature modeling is one of the trends of CAD technology and design based on feature plays an important role in modern CAD/CAM. In this paper, the definition and classification of features on the base of industrial application are discussed, with which the methods of modeling based on features are studied, a new type of data structure supporting feature modeling is presented and an method—dynamic topologic information processing method for processing topologic information is studied.
