摘　　要：为增强Auto CAD设计功能,提高图纸绘制速度、精确度和灵活度,以轴类零件为例,对Auto CAD中典型零件参数化设计功能进行研发,采用面向对象的VB语言,在Auto CAD中开发了轴类零件参数化设计程序,以轴类零件的典型特征为基本图元参数,各图元按顺序一一衔接完成图形绘制,从而达到参数化设计目的。通过减速箱典型实例说明该方法可提高Auto CAD中轴类零件的多样化绘图效率,增强Auto CAD的设计智能化程度,方便设计人员使用。In order to improve the function of AutoCAD in drawing speed,accuracy and flexibility,this study develops a program of parametric design of typical axial parts parameterization in AutoCAD interface using VB language.The typical characteristic of axis parts is designed as basic primitive and parametric design is achieved by order joining every primitive together.A gearbox example shows that this method can improve efficiency of diversity of axial parts and intelligent level of AutoCAD as well as convenience for designers.
