缺少自定义函数

已补上欠缺的自定义函数

自贡黄明儒

觉得太复杂了

自贡黄明儒

仅供参考
;;示例(HH:delLwpolyPt1 (car(setq en(entsel))) (cadr en))
(defun HH:delLwpolyPt1 (en p / ENT L1 L2 P1)
  (setq ENT (entget en))
  (setq p (vlax-curve-getclosestpointto en (trans p 1 0)))
  (setq p1 (HH:PickClosePt en p))                            ;离p最近的顶点
  (setq p1 (list 10 (car p1) (cadr p1)))
  (setq L2 (cdr (member p1 ent)))                            ;后段
  (setq L1 (reverse (cdr (member p1 (reverse ent)))))            ;前段
  (entmod (append L1 L2))
)
http://bbs.mjtd.com/thread-108149-1-1.html见HH:PickClosePt

小朱的心思

HH:PickClosePt这个函数没有啊
