摘要
在现有的AutoCAD资料和图书中,甚至在AutoCAD的帮助系统中,都没有Spline(样条)曲线的程序画法.在比较了circle命令的手工画图用法和程序画图用法后,介绍了一种用AutoLISP语言在AutoCAD中画任意多点的Spline曲线的新方法,并给出了程序代码.使用该方法可以在一个大型绘图软件中由程序自动画出任意多点组成的任意多条Spline曲线.
Drawing splines in programs could not be seen in the present materials and books of AutoCAD, even in the Help system itself. By comparing the man and program drawing methods of ′circle′, a new method of drawing splines of any points by using AutoLISP program language was introduced in this paper. And the program source code was also given. This method could automatically draw any splines of any points in programs for the large drawing software.
