摘要
本文提出一种参数化绘制螺旋叶片展开图的方法及其计算机应用程序。该程序用VBA语言编写 ,在AutoCAD环境下运行 ,一旦调用 ,即可按给定的螺旋叶片的外径D、轴径d、螺距S ,自动计算图形尺寸及确定绘图比例 ,从而绘出有完整尺寸的螺旋面展开图。
This paper propose one parametric method of drawing a expanded view of helix vane and its programme on application.The programme was written in VBA and run under AutoCAD.Once being transferred ,it could automatically compute the size of the drawing and make sure its proportion according to the given parameter--D?d?S of helix vane,thus drawing one expanded view of helicoids with intact size.
