【摘要】 文中描述了产成式设计中的几类特征编辑操作的结构,并设法将所有因特征发生交互作用而引起的面的拓扑变化(如融合、分割)引入一种类命名机制,它在基于特征造型系统中起到标识实体模型中的拓扑实体和检验拓扑实体存在的合法性的作用.更多还原

【Abstract】 ： In this article,we describe the structure of editing operation in featured＿based generative design,manage all the topological changes of faces such as merging and spliting caused by feature interactions,using a generic naming scheme.The generic naming scheme plays the following important roles in a feature＿based modeling system,Identify topological entities of solid model and Check the validity of design features caused by feature interactions．更多还原
