摘要
在系统实现的基础上 ,提出一种依据设计过程确定约束依赖关系的参数化设计模型 ,建立约束和图元之间的映射模式 ,优化确定节点之间的更新从动性 ,从而降低约束求解的复杂度 .用户添加的约束和系统自动识别的约束能动态添加到有向约束图中 ,并支持任意图形块的选择重复 .实践证明 ,该模型算法简单 ,交互性好 ,能很好理解用户的设计意图 .
The present paper covers a new parametric design model based on system realization, which forms the relationship of constraints' mapping according to the design process, maps the constraints to graphical unit so as to update the design with a more suitable way, and reduces the complexity of the constraint solver . The system could add the constraints that user defined and the system identified simultaneously, and offer the function of copy the sub graph. The practice proved that this model is simple and shows a quick interactive speed, it could catch on the design purpose more exactly.
