【摘要】 文章论述了一种面向对象的参数化设计方法。采用基于有向无环超图的约束表示 ,完整的建立参数化模型 ,不仅可以表示简单约束关系 ,还可以方便的表示元素间的双向约束。在交互绘图的过程中获取约束关系并保存 ,实现参数驱动。利用功能强大的 Object ARX[1 ] 进行 Auto CAD上的二次开发 ,采用面向对象的技术 ,充分利用Object ARX的类库 ,有效发挥其封装性和扩展性 ,在 Windows环境下和 VC+ +结合编程 ,实现参数化设计。更多还原

【Abstract】 We discuss the object-oriented parametric design.using the constraints representation based on the directed hypergraph,we create the parametric model completely.The way can express not only the simple constraints but also the bi-directional constraints.During the process of the mutual drawing,we can record the constraints and implement parameter-driven graphics.By making use of the power ObjectARX,we make the exploitation based on AutoCAD.Using the Object-oriented technology and the class llibraries,we can efficiently exert encapsulation and extension and implement the parametric design based on Windows and VC++.更多还原
