AutoLISP手指图案，代码如下。
(defun c:test()
(setvar "cmdecho" 0)
(setq os (getvar "osmode"))
(setq oldlayer (getvar "clayer"))
(setvar "osmode" 0)
(setq cenpt (getpoint "圆心："))
(setq dia (getpoint "\n直径<96>:")) (if (null dia) (setq dia 96))
(setq n (getint "\n手指头数目<4>:")) (if (null n) (setq n 4))
(command "-layer" "m" "str" "c" 4 "" "")
(command "circle" cenpt "d" dia)
(setq ent (entlast))
(setq r (* dia 0.5) x1 (/ r n) x2 (* x1 0.5))
(setq k (- r x2) p0 cenpt)
(setq i 1)
