摘要
在本文中作者讨论了基于图形元素特征参数的参数化设计方法。图形元素的特征参数能反映图形的几何和拓扑信息 ,根据图形元素的特征参数建立相关的图形元素类 ,并建立图形之间的各种约束关系 ,当选择某一图形元素后 ,参数化系统自动完成图形搜索 ,利用图形元素特征参数和相关的约束建立并求解约束方程 ,实现图形参数化。该方法操作简单 ,已用于参数化草图系统中 ,在VC
In this paper,parametric design method based on feature parameters of drawing elements is discussed.Feature parameters of drawing elements can reflect geometrical and topological information of a drawing.According to feature parameters,classes of drawing elements and all kinds of constrainsts are built.When an element is selected,parametric system can serach the drawing automatically,then constraint equations can be established and be solved with characteristic parameters,and create a parametric drawing.The method is simple,which is used in parametric sketch system that is finished with visual C.
