摘要
提高特征编辑的效率是基于特征的参数化系统的关键技术.本文提出一个基于边界模型(Brep)、构造历程树(CSG)和特征描述图(FDG)的特征模型.基于FDG的特征设计和编辑克服了传统特征造型系统的时序性和历史流的管理顺序,是一个与历程无关、非时序性的特征造型技术.
Improving on the efficiency of feature editing has been regarded as the key technology of parametric design system. This paper presents a feature model based on boundary represent(Brep), construct solid geometry(CSG) and feature describing graph(FDG), which gets over the history-based order of traditional feature modeling and which is a technology of history-independent and history-independent feature modeling.
