AutoLISP矩形与多个内切圆，代码如下。
(defun c:test()
(setvar "cmdecho" 0)
(setq oldlay (getvar "clayer"))
(setq oldosmode (getvar "osmode"))
(setvar "osmode" 0)
(setq w (getreal "输入底部宽度<100>:"))
(setq n (getint "\n几排垂直圆<2>:"))
(setq rp1 (getpoint "\n输入左下角点："))
(if (null w) (setq w 100))
(if (null n) (setq n 2))
(setq r (/ w 2 (1+ (* (sqrt 3) (1- n)))))
(setq cp1 (polar rp1 (/ pi 4) (* r (sqrt 2))))
(setq cp2 (polar cp1 (/ pi 6) (* r 2)))
(setq rp2 (polar rp1 0 w))
(setq rp3 (polar rp2 (/ pi 2) (* 4 r)))
(setq gap (* 2 (sqrt 3) r))
(command "-layer" "m" "str" "c" 4 "" "")
(command "rectang" rp1 rp3)
(command "circle" cp1 r)
(command "array" (entlast) "" "r" 2 n (* r 2) gap)
(command "circle" cp2 r)
(if (> n 2) (command "array" (entlast) "" "r" 1 (1- n) gap))
(command "-layer" "m" "dim" "c" 1 "" "")
(command "dim1" "hor" rp1 rp2 (polar rp1 (* pi 1.5) 10) "")
(setvar "somode" oldosmode)
(setvar "clayer" oldlay)
)
代码完。
