有何意义？

意义当然有呀。可以更方便的操作三维实体。。。可以了解桌子公司的程序的结构。。说不定这里有CAD的核心技术呢。

走都不会，想跑啊

如果是优秀的数据结构，桌子公司 不会藏着 不用。一定是数据结构本身有问题。

走谁不会。

这是ACIS实体的数据，当时Autodesk购买使用权。其实也没什么神秘的，下面的函数就能将其解码，但没啥用，最多能得到长方体的长宽高等数据。如果你使用AutoCAD命令acisout将目标实体输出成SAT文件，里面显示差不多的内容。

；其中data就是我们通过entget的到数据
(defun decode-code-ele-data (data / liste)
  (foreach n data
    (progn
      (if (= (car n) 1)
        (setq liste (cons (cons 1 (decode-code-acis (cdr n))) liste))
        (setq liste (cons n liste))
      )
    )
  )
  (reverse liste)
)
(defun decode-code-acis        (s / n l)
  (setq n "")
  (while (> (strlen s) 0)
    (setq l (substr s 1 1)
          s (substr s 2)
          n (strcat n
                    (if        (= " " l)
                      " "
                      (chr (- 159 (ascii l)))
                    )
            )
    )
  )
)

行家一出手，就知有没有。

skymudy

谁还知道更多这方面的资料呀，我急需啊

skymudy

我正要寻找用lisp  vlisp中关于三维操作的资料，我想编个三维建模修改出图的小程序
