三维实体被拉伸后数据怎么发生了变化，点坐标都不对了，如何解决？？？

(GETACISDATAONLY (ACISDECODEENT ORENT 楼主能提供一下这两个函数吗

挚友01 · 发表于 2023-9-25 12:06

(defun GETACISDATAONLY (ENT)
  (setq TMP ())
  (foreach @@ ENT
(if       (equal (car @@) 1)
   (setq TMP (cons @@ TMP))
)
  )
  (setq TMP (reverse TMP))
  (setq       TMP1 (car TMP))

  (setq  TMP  (cdr TMP)
      TMP  (cdr TMP)
      TMP  (cdr TMP)
  )
  (cons TMP1 TMP)
)
(defun ACISDECODE (ST / LN N C ST1)
  (setq       ST1 ""
      N (strlen ST)
  )
  (while (> N 0)
(setq C (ascii (substr ST N 1)))
(setq ST1
         (strcat
         (cond
            ((= C 32) " ")
            ((= C 86) "I")
            ((chr (boole 6 C 95)))
         )
         ST1
         )
)
(setq N (1- N))
  )
  ST1
)

ACISDECODEENT 这个不对吧

能把完整的代码发来吗，里面还差一些函数，例如str_sel

挚友01 · 发表于 2023-9-25 15:57

(defun str_sel(val1 val2 / val1 val2 c n cc v1 v2)
(if (and val1 (/= val1 "")(/= val1 " "))
  (progn
(setq n "T" c 1)
(setq v1 (strlen val1) v2 (strlen val2))
(while (and n (<= c v1))
   (if (= (strcase (substr val2 1 1))(strcase (substr val1 c 1)))  ; 当第一个字符相同时
      (if (<= (+ c (- v2 1)) v1)
      (if (= (strcase val2)(strcase (substr val1 c v2)))
         (setq n nil cc c)
      )
      )
   )
   (setq c (+ c 1))
)
cc
) )
)
这个只是字符查找，上面的代码也是从网上找的...

ACISDECODEENT 是做啥的？

挚友01 · 发表于 2023-9-30 09:45

有没有“重画”，将所有的拐点恢复到【正常】的位置。。。
