转帖：用LISP对CAD进行二次开发

cad

刚开始工作时候，经常使用AutoCAD2002设计，
9 F* Y6 D& v+ d4 f: `" }制作标题栏、画粗糙度符号是一个重复性的工作
而CAD到又没有提供相关的命令可以让我们的操作一步到位，很不方便
% ]+ Q- K' J2 I( r$ U3 m于是，我就利用在学校里所学的Autolisp知识，自己开发了两个小程序
只要把它们保存为扩展名为lsp的文件，放在CAD安装目录下面，
并在“加载应用程序”中，将其设为“启动组”即可使用

制作标题栏请用tk命令，可以选择标题栏所需的图号、布局（横排、竖排）
- M" r4 L/ m  h$ }5 M: Z里面签名中是本人的名字，大家可以打开代码更改成自己的姓名
3 K: @1 S8 Y' V标题栏还可以自己插入时间，很方便
大家输入这个命令以后，就已经自动为您设置了常用的线型及图层
字体也配置好了：我们机械制图一般用长仿宋体

再说粗糙度符号的开发
粗糙度符号我在原稿完成之后
突然又想到加一段代码
可以实现在正交位置和任意位置插入粗糙度符号的功能
方法是按F8或者点南最下面的"正交"按钮
5 r. T( E2 p3 a9 W要使用本命令，只需输入cu即可

应该是图框插入点程序下面中某一语句出现问题了，和源程序再比对一下吧。不行的话就另设一打印语句放在其下面某一处，找到出错语句。改一下就好了
