摘要
本文介绍实体造型中引入形状特征的局部操作，研究了包含形状特征描述的数据结构，分析了形状特征的分类、框架、特征间的联系及有关操作，分析了欧拉运算及实现思路，在此基础上对实体造型作局部操作．提高了造型功能和运算效率，也对特征造型作了相应的探讨．
The local operation in solid modelling with shape-feature was introduced in thispaper.The data structure including the description of shape-feature was established. Theclassification,the frame,the relation and some operation of the shape-feature wasanalyzed.The Euler Operation and its realizing method was introduced. Based on theshape-feature,the local operation in solid modelling was accomplished. In addition, thefeature modelling was studied.
