帮我用autolisp写一个CAD画出一个人手拿二氧焊机的焊枪的代码

好的，以下是基于AutoLISP语言编写制作二氧焊机的CAD图纸的代码：

(defun c:drawweldgun (/)
  (setq pt1 (getpoint "\n指定人物的位置："))
  (setq pt2 (getpoint "\n指定焊枪的位置："))
  (command "line" pt1 pt2 "")
  (setq pt3 (getpoint "\n指定焊枪的长度："))
  (setq pt4 (polar pt2 (angle pt1 pt2) pt3))
  (command "line" pt2 pt4 "")
  (setq pt5 (polar pt4 (+ (angle pt2 pt4) (/ pi 2)) 0.25))
  (setq pt6 (polar pt5 (angle pt2 pt4) (* (distance pt2 pt4) 0.8)))
  (command "pline" pt4 pt5 pt6 pt4 "")
  (setq pt7 (polar pt6 (+ (angle pt2 pt4) pi) 0.15))
  (command "circle" pt7 0.15 "")
  (setq pt8 (polar pt7 (+ (angle pt2 pt4) (/ pi 2)) 0.1))
  (setq pt9 (polar pt8 (angle pt2 pt4) (* (distance pt2 pt4) 0.2)))
  (command "pline" pt8 pt9 pt6 "")
  (setq pt10 (polar pt8 (+ (angle pt2 pt4) pi) 0.05))
  (command "rectangle" pt10 pt9 0.05 "")
  (setq pt11 (polar pt9 (+ (angle pt2 pt4) pi) 0.05))
  (command "line" pt9 pt11 "")
  (setq pt12 (polar pt6 (+ (angle pt2 pt4) pi) 0.05))
  (command "line" pt6 pt12 "")
  (setq pt13 (polar pt12 (angle pt2 pt4) (* (distance pt2 pt4) 0.2)))
  (command "pline" pt11 pt13 pt12 "")
  (setq pt14 (polar pt13 (+ (angle pt2 pt4) (/ pi 2)) 0.1))
  (setq pt15 (polar pt14 (angle pt2 pt4) (* (distance pt2 pt4) 0.2)))
  (command "pline" pt14 pt15 pt13 "")
  (setq pt16 (polar pt15 (+ (angle pt2 pt4) pi) 0.05))
  (command "rectangle" pt16 pt15 0.05 "")
  (setq pt17 (polar pt15 (+ (angle pt2 pt4) pi) 0.05))
  (command "line" pt15 pt17 "")
  (setq pt18 (polar pt13 (+ (angle pt2 pt4) pi) 0.05))
  (command "line" pt13 pt18 "")
)

以上是基于AutoLISP语言编写制作二氧焊机的CAD图纸的代码，你可以将这段代码复制到AutoCAD中的AutoLISP编辑器中，然后执行"drawweldgun"命令，按照提示输入所需参数即可。
