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，
! w8 M) X' i9 f3 k6 Q3 s2 _: E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
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，
6 V) E6 k, M# F5 i! ~  S8 ~, ]* Q并在“加载应用程序”中，将其设为“启动组”即可使用

9 _* B" c/ D: E' `% p  e, N5 ^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）
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
标题栏还可以自己插入时间，很方便
- v: \; Z) r& w0 ^6 V  G+ n3 C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
$ @* h) R$ A1 m9 t. V" e" P
# p5 t/ J* ]9 }6 w/ r* q. D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
! K7 C. x& m5 b. [1 p可以实现在正交位置和任意位置插入粗糙度符号的功能
3 @2 u" b1 E6 _+ y# q7 D0 W方法是按F8或者点南最下面的"正交"按钮
要使用本命令，只需输入cu即可

下面是程序代码：

如何使用啊，我加载了，执行后没有显示图框，怎么回事，请指教，谢谢

lexola

显示出
请输入图框左下角的插入点; error: bad argument type: numberp: nil

什么意思啊

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
