CAD中参数化绘制立体渐开线齿轮

The stereoscopic involute gear is draw in the parameterization among the CAD

绘制立体渐开线齿轮展示了参数化绘图中处理图形的巧妙构思和设点、点坐标表示的技巧;它介绍了定义原Lsp语言中没有的函数,建立简易实用的数据库和从中提取相关数据以及怎样参数化编程绘制三维立体图形;它显示了Lsp语言在CAD绘图中的魅力。

drawing the stereoscopic involute gear shous that masterly conceiptions of the figure that handle in the parametric mapping ,and techniques of using points and point coordinate for expression . It introduces new functions which are not defined in the old Lsp language, creates a simple and practical database and shows us how to select correlative data and how to draw 3D stereoscopic graphs by parameterization programming ; it reveals Lsp language has great charm in CAD's mapping .
