利用VBA实现特殊曲线的自动绘制

Auto-drawing Special Curves Using VBA

在AutoCAD中利用VBA开发环境 ,通过分析特殊函数曲线的性质 ,选择B样条曲线作为绘图的基本对象 ,在适当的设置对象的属性和方法的基础上 ,利用迭代插值的方法绘制圆滑的拟合曲线。在保证精度的同时提高了存储效率 ,提供了一种在AutoCAD下自动绘制特殊曲线的方法。

Auto-drawing special curves using VBA developing enviorment in AutoCAD, with parsing the character of special curves for function , we select B-spline curve as the basic object of drawing . On the base of setting attributes and methods of object properly, we use iterated interpolating function to draw smooth fitting curve, with ensuring the precision and improving store efficiency,we can draw normal-distribution curves very satisfiedly at one time. we present a method to auto-drawing special curves in AutoCAD.
