摘要
针对尺寸之间的关联约束 ,本文首先分析了尺寸链约束的特点 ,提出了基于尺寸链的尺寸环模型 .通过对尺寸和被约束图形对象的识别与理解 ,研究了尺寸链、尺寸环建立和尺寸环中的尺寸到被约束元素之间的约束关系的映射算法 。
The characteristics to dimension chain constraint is analysed, dimension loop model is put forward based on the dimension chain for solving dimension relationship constraints . By the identification of dimension and other graph object , algorithms are given for building the constraint relationship between dimension and entity,dimension and dimension ,entity and entity . With the dimension loop model, mapped relation between concealed relation dimension constraints and bound graph elements can be achieved.
