在Visual LISP环境下的编制三维变径螺旋线程序

Using Visual LISP in AutoCAD 2000 to Program 3D Spiral

介绍了用AutoCAD 2 0 0 0中的VisualLISP开发工具开发三维圆柱、圆台螺旋线和平面蜗卷线程序 ,给出了开发程序代码和运行结果 ,以及用该程序在AutoCAD2 0 0 0中绘制三维圆柱弹簧、三维圆台弹簧。

The paper deals with using Visual LISP, a development tool in AutoCAD 2000 to develop 3D cylinder, truncated cone spiral and 2D spiral-shaped line, illustrates program code, functioning results, and how to map 3D cylindrical spring, 3D truncated cone spring, spiral burr and 2D spiral-shaped spring.
