cad中的外部参照怎么分解啊,多重外部参照，X命令没用，求高手留下QQ或邮件帮忙分解掉

新建txt文本文件，将下面内容复制粘贴到里面，然后重命名文件名为exm.lsp
在 cad中load加载这个lsp文件，或是将exm直接拖入cad窗口，
之后命令行输入exm，回车后按提示操作即可。

;;-------------------------------------------------------------
;;转换“多重插入块”为“普通块”。
(DEFUN C:exm ()
(setvar "cmdecho" 0)
(SETQ STM (car (ENTSEL "\n点取多重块")))
(while stm
(setq e (entget stm))
(setq stlx (cdr (assoc 0 e)))
(if (= stlx "INSERT")
(PROGN
(setq r_zm70 (assoc 70 e))
(setq c_zm71 (assoc 71 e))
(setq r_dist_zm44 (assoc 44 e))
(setq c_dist_zm45 (assoc 45 e))
(setq e (subst (cons 44 0) r_dist_zm44 e))
(setq e (subst (cons 45 0) c_dist_zm45 e))
(setq e (subst (cons 70 0) r_zm70 e))
(setq e (subst (cons 71 0) c_zm71 e))
(setq e (subst (list 100"AcDbBlockReference") (list 100"AcDbMInsertBlock") e))
(entmake e)
(entdel stm)
))
(SETQ STM (car (ENTSEL "\n点取下一多重块")))
)
(setvar "cmdecho" 1)
)

【XREF】打开【外部参照】。
在【外部参照】管理器中绑定外部参照，就可以炸开。
