用AutoLISP编程绘制两圆柱相贯线及表面展开图

Drawing the Interpenstrating Line and Unrolled Diagram of Two Cylinders by AutoLISP

介绍利用ＡｕｔｏＬＩＳＰ语言编写程序，在ＡｕｔｏＣＡＤ中实现参数化绘图的方法，实现自动处理并绘制等径正交、异径正交、异径偏交的两圆柱全贯时相贯线和展开图。

This paper introduces a new method which can use the language of AutoLISP to program parameters and can automatically draw relevant interpenetrating lines and unrolled diagrams when two cylinders interpenetrate each other with various diameters in AutoCAD.
