(defun c:wSave(/ pzx pys p1 p2 p3 p4 s s1)
  (setq pzx (getpoint "\n选择左下角点(用鼠标直接点取或在命令行输入):"))
  (setq pys (getpoint "\n选择右上角点(用鼠标直接点取或在命令行输入):"))
  (setq p1 (list (- (car pzx) 0.01) (- (cadr pzx) 0.01)))
  (setq p2 (list (+ (car pys) 0.01) (- (cadr pzx) 0.01)))
  (setq p3 (list (+ (car pys) 0.01) (+ (cadr pys) 0.01)))
  (setq p4 (list (- (car pzx) 0.01) (+ (cadr pys) 0.01)))
  (command "rectang" pzx pys)
  (setq s (ssget "L"))
  (command "trim" s "" "F" p1 p2 "" "F" p2 p3 "" "F" p3 p4 "" "F" p4 p1 "" "")
  (command "erase" s "")
  (setq s1 (ssget "WP" (list p1 p2 p3 p4 p1)))
  (rder s1)
  (setq s nil s1 nil)
  (setvar "FILEDIA" 0)
  (command "SaveAs" "" "d:\\test" "close" "n")
  (setvar "FILEDIA" 1)
  (princ)
);end wSave
  (defun rder(s1 / s2 ent s3 n)
   (setq s2 (ssget "X"))
   (if (not s1) (command "erase" s2 "")
   (progn
  (setq s3 (ssadd) n 0)
  (repeat (sslength s2)
  (setq ent (ssname s2 n))
  (if (not (ssmemb ent s1))
(ssadd ent s3)
  )
(setq n (1+ n))
  )
(command "erase" s3 "" "redraw")
