如何求选择集中图形的坐标角点
如何求选择集中图形的坐标角点，图形是任意图形，并且选择集中图元数量比较多，不低于1000个。麻烦高手能给个思路，要是有代码就更完美了。多谢！！http://bbs.mjtd.com/xwb/images/bgimg/icon_logo.png 该贴已经同步到 用户5694667304的微博 选择集的实体外矩形框 by gxl
(defun MJ:GetssBox (ss / i l1 l2 ll ur)
(repeat (setq i (sslength ss))
(vla-getboundingbox
(vlax-ename->vla-object (ssname ss (setq i (1- i))))
'll
'ur
)
(setq l1 (cons (vlax-safearray->list ll) l1)
l2 (cons (vlax-safearray->list ur) l2)
)
)
(mapcar '(lambda (a b) (apply 'mapcar (cons a b)))
'(min max)
(list l1 l2)
)
