基于面向对象技术的参数化CAD系统

Parametric CAD System Based on Object-Oriented Technology

通过分析参数化绘图的原理及方法 ,讨论了基于面向对象技术的CAD系统如何实现产品结构的参数化绘图 ,采用高级语言VisualBasicApplication(VBA)与AutoCAD数据接口技术 ,实现了齿轮系列产品结构的二维、三维展开图等的参数化设计。

Through analyzing principle and way of parametric drawing,discusses the CAD system how to realize parametric drawing based on object oriented technology. Adopt data connection technology of visual basic application(VBA) and AutoCAD, and then realize parametric design of gear serial product structure two dimension and three dimension and so on.
