采用Autolisp语言生成平面与圆锥截交线的二次开发

The Secondary Development of the Intersection of Plan Cross Cone Generated by Autolisp Language

研究了AutoCAD平台下基于纬圆法思想的平面与圆锥截交线的自动绘制程序。Autolisp语言程序实现了抛物线、双曲线的自动绘制。为绘制平面与圆锥截交线的绘制提供了一种减少重复性劳动的有效方法。

The automatic drawing program of the intersection of plan cross cone,based on latitudinal circle methodin AutoCAD,hasbeen studied.The Autolisp program can realize the automatic drawing of parabola and hyperbola and provide an effective method for the drawing of the intersection of plan cross cone to reduce repetitive work.
