(defun c:test()
(setq pt1 (getpoint "\n基准点:"))
(setq pt2 (getpoint "\n圆半径点:"))
(setq cir_d (* 2 (distance pt1 pt2)))
(setq ang (angle pt1 pt2))
(setq dd (getdist pt1 "\n圆间距:"))
(setq nn (getint "\n重复次数<10>:"))
(if (null nn) (setq nn 10))
(setq cc 1)
(repeat nn
(setvar "cecolor" (rtos cc 2 0))
(setq pt2 (polar pt1 ang cir_d))
(command "circle" "2p" pt1 pt2)
(setq cir_d (+ cir_d dd))
(setq cc (+ 1 cc))
)
(setvar "cecolor" "bylayer")
(prin1)
)
代码完。
