转帖：用LISP对CAD进行二次开发
刚开始工作时候，经常使用AutoCAD2002设计，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，
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）
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
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
要使用本命令，只需输入cu即可
下面是程序代码：
标题栏：
(defun c:tk()
(command "layer" "c" 9 "0" "lw" 0.3 "0"
"m" "中心线" "c" 1 "" "l" "center" "" "lw" 0.09 ""
"m" "虚线" "c" 4 "" "l" "ACAD_ISO02w100" "" "lw" 0.09 ""
"m" "标注" "c" "blue" "" "lw" 0.09 ""
"m" "细实线" "c" "6" "" "lw" 0.09 ""
"s" "0" "")
(command "style" "s3" "仿宋_GB2312" "3.5" "0.67" "0" "n" "n" "n" "")

下面是粗糙度符号代码：

(command "osnap" "nea");设置捕捉模式为捕捉最近点
(setq a1 (getpoint"请用鼠标点取插入点:"));用鼠标获取插入点
(command "osnap" "off")关闭捕捉模式
(setq bb(getpoint "请用鼠标选择插入方向,"));确定插入方向，与待标示表面垂直
(setq an1 (angle a1 bb));定义角度an1,该角度为x轴与插入方向的夹角
(setq ot1 (getvar "orthomode"));获取正交模式的值
;如果正交模式打开，则更改方向，使之处于正交方向
(if (and (= ot1 1) (or (> an1 (* pi 1.75)) (< an1 (* pi 0.25)))) (setq an1 (* pi 0)) )

xiexie!
谢谢！
太有帮助了！谢谢！:handshake 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 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 顶一下！！！！！！！！:victory: 很不错,赞一个! 谢谢！谢谢！谢谢！ 谢谢分享！ 学习了。 谢谢分享！ 学习了。
回复 #5 lexola 的帖子
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 谢谢版主的分享，收藏了，好东西绝不放过！:lol 谢谢楼主，我一直都希望能学cad二次开发，却找不到这方面的书。:'( :'( 谢谢分享！ 学习了。 好像很高深喔。下来学习。
