特征造型中拓扑元素和约束关系管理体系

The Management System of Topological Entities and Constraints in Feature-Based Modeling

在特征造型过程中,随着造型体数目的增加,设计模型将变得越来越复杂。为了能够正确地维护设计者的设计意图,提出了一种新的拓扑元素与约束关系管理体系。并给出了在此种管理体系下,特征拓扑元素编码和约束关系维护方法。将这种方法应用于造型过程中,必将使系统的设计效率有大幅度的提高。

In the process of feature-based modelling,with the increasing number of features,the design model becomes more and more complex.In order to maintain the intent of designer,a new management system of topological entities and constraints is put forward.Measures to ensuring the consistency of names and constraints of topological entities are illustrated.The new management system effectively improved the running efficiency of design process.
