cad中多重插入块分解不了

把以下内容保存为lsp文件,加载后运行exm既可把，然后既可用“explode”分解。
;;-------------------------------------------------------------
;;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))

是这样的啊，如果是单村的多重插入块，你可以在属性框里将行列数调整为1，或者重新插入一个此名的图块，这样就可以分解了。如果块名前带星号，是匿名块的话，那就没办法了。
