摘要
本文提出了特征柔性模型，介绍了它的结构和组成部分，并给出了特征柔性模型的表达实例。该模型使用面向对象方法，将约束方法有效地封装在数据结构中，而将对约束方法处理的通用程序分离出来，能有效地表达较为复杂的二维形状特征，同时支持用户在线扩展特征。
The feature flexible model is proposed, its
structure and its compon ents are introduced. An example of this model is given in this paper. This
model is built by object oriented method. Constraints methods are encapsulated in data structure,
and processing program is separated. Two dimension complex sh a pe feature can be expressed
effectively by this model, at the same time, dynamic extending the model is supported.
