Lisp语言在CAD绘制征地图中的应用

Lisp语言采用普通的文本编辑器编程,程序内容易读易懂,生成执行文件后能有效防止程序被误改,是征地图参数化绘图的首选编程语言。文章以高速公路施工临时用地的征用和复垦工作为例,结合临时用地的工作流程和绘图参数的采集方法,对lisp在CAD二次开发中的应用进行阐述。

Application of Lisp Language in CAD Drawing of Expropriation Map

Lisp language used the ordinary text editor for the programming, the program content is easy to read and understand, and it can effectively prevent the mis-modification of programs after the execution files are generated, which thus is the preferred programming language for the parametric map drawing.The article,with the expropriation and rehabilitati-on work of temporary expressway construction land as the example,and in combination with the workflow of temporary land and the acquisition methods of drawing parameters, it de-scribed the application of Lisp in CAD secondary development.
