摘要: 分析了传统的基于历史流管理的特征造型系统的缺陷和不足,提出了语义特征模型的分层体系结构,详细解释了语义特征模型的概念、使用方法和应用范围,阐述了特征依赖图、持久性ID、拓扑几何特征模型和Cellular模型的概念与应用。最后,建立了特征操作的过程模型。

关键词: CAD, 特征造型, 语义模型, Cellular模型, 持久性ID

Abstract: We first analyzed the limitations of history-based modeling system. Then we presented the structure of semantic feature model, including the concept and the application of Feature Dependency Graph, Persistent ID system, Feature Topology model and Cellular model. At last, we constitute the process modeling of the feature operation.

Key words: CAD, feature modeling, semantic model, cellular model
