摘要
提出一种直接操作特征过程中将操作局部化的方法,该方法利用语义造型系统中特征依赖图及细胞表示特征的高效性,将发生变化的区域从特征模型中分离出来.利用该方法使得直接操作特征时缩小了对模型进行约束求解的范围,从而满足了直接操作特征时对约束求解的速度要求.同时,通过对数据结构的分析,给出两个相应的分离算法.
In this paper, a method of localizing manipulation when directly manipulating features was presented. This method separated the changed cells from the Feature Model by making use of high efficiency of the cellular representation and Feature Depended Graph (FDG). And it reduced the scope of resolving constraints of the model when directly manipulating the feature. As a result, this method improved efficiency and satisfied the need of resolving to constraint. Meanwhile, two separate algorithms were given after analyzing the interrelated data structure.
