我在CAD2002画图中突然停电,然后重新起动后刚画图的文件就打不开了,一打开就有如下对话框:Unable to lood this drawg file because it contains incorrect or corruptel in fomation :<D\李小华\02.dwg>.The technical problem detectedis:D:李小华\02.dwg.The"Recover damaged drawing ".Selection may be used to restore undamaged material from this file :<D\李小华\02.dwg>.我一确定就什么都没有了,这样的问题出现了三次,请各位大侠帮忙,十分感谢!
