(defun c:test()
(setvar "cmdecho" 0)
(setq pt1 (getpoint "\n第一点："))
(setq pt2 (getpoint pt1 "\n第二点："))
(setq ll (distance pt1 pt2))
(setq ang (angle pt1 pt2))
(setq pt3 (polar pt2 (+ ang (/ (* 120 pi) 180)) ll))
(command "polygon" 3 "e" pt1 pt2)
(command "arc" pt1 "e" pt2 "a" 180)
(setq en1 (entlast))
(setq mid1 (polar pt1 ang (/ ll 2)))
(command "circle" "2p" mid1 (polar mid1 (+ ang (* pi 1.5)) (/ ll 2)))
(setq en2 (entlast))
(setq mid2 (polar pt2 (+ ang (/ (* 120 pi) 180)) (/ ll 2)))
(setq cen (inters pt3 mid1 pt1 mid2))
(command "array" en1 en2 "" "P" cen 3 "" "")
(prin1)
)
代码完。
