基于Auto LISP的AutoCAD参数化绘图

Parametric Drawing based on Auto LISP in AutoCAD

通过对Auto LISP语言的分析与研究,探讨了基于Auto LISP的AutoCAD参数化绘图程序设计的基本步骤。本文以钣金折弯件的参数化绘图为例,应用LISP语言编写工程图的参数化绘制程序,应用DCL语言创建人机交流的对话框,并且详细阐述了其实现过程。实践表明,Auto LISP语言功能强大,易学易用,是AutoCAD二次开发的重要工具。

Through analyzing Auto LISP language, discussing program design basic steps of parametric drawing based on Auto LISP in AutoCAD. This paper takes the parametric drawing of sheet metal bend components as the example which applies LISP language compile parametric drawing programs, and DCL language create a man-machine exchange dialogue frame. Moreover. its realizing process is presented in detail, The practice indicates the function of Auto LISP language is powerful, and which is easy to study and use, and is an important tool of redevelopments in AutoCAD.
