摘要
针对门窗立面图形绘制的自动参数化水平不高,利用特征造型的基本原理,结合表达式运算,本文定义了门窗立面的数据结构,并以此为基础,实现了门窗CAD系统图形的尺寸驱动和自动参数化.讨论了详细的算法,并指出了该算法尚需继续深化之处.
Based on principles of feature modeling and expression solution,a new approach of parametric drawing is presented. Firstly it defines the data structure of windows profile, then a general algorithm about parametric drawing, dimension driven is introduced. At last it pointes out some problem under.
