摘要
就相交圆柱、圆锥体参数化绘图命令的Lisp二次开发,给出了相交圆柱及圆锥表面的相贯线算法的参数公式和实现参数化绘制三视图程序设计思路,对实现参数化绘图所涉及到的一些关键问题给出相应的处理方法,对绘图命令的不同参数输入及对应的相贯线绘图结果进行分析;该命令以对话框输入初始参数,能实现自动绘制圆柱、圆锥体及其相贯线三视图、尺寸标注及将主要尺寸、参数及相贯线的坐标数据写入数据文件.
For secondary development of a parametric drawing command of a complex object,which was composed of a cylinder and a cone,the formula of the intersection curve was given and the Lisp program structural diagram of parametric drawing of multiview was delivered,some processing methods coping with several key problems of drawing of intersection curve was listed.Different intersection line result in connection with different parameters' entry were analyzed.The command has the functions of multivew drawing,dimensioning and writing main parameters and coordinate data of intersection line to a data file.
