摘要
为了提高设计效率,提出一种全参数化设计方法,系统阐述其实现机理,给出自动施加约束、约束实时显示及约束可视管理算法。并运用AutoCAD二次开发技术,将几何约束求解器CBA和CAD绘图平台有机结合,实现全参数化绘图。
A kind of method for fully parametric design is proposed to improve the efficiency of draft design.In this paper,the implementing mechanism is systemically depicted.Some key algorithms,such as auto-inflicting constraint on entities,displaying geometric constraint between entities and visual management of constraints,are also described in-depth.Finally,the fully parametric drafting system is realized by organically integrating the geometric constraint solver（CBA） and AutoCAD based on the second development technology for AutoCAD.
