悬赏高分解决cad打开错误！（急啊）

我的cad图无法打开，诚邀各位高手相助！
打开会出现“无法打开此图形，它包含不正确或已损坏的信息，recover命令能够恢复此图形中未损坏的内容”
但用recover命令会出现：
Reading handle 1 object type AcDbBlockTable
Error 13 (eUnknownHandle) Object discarded
Missing AcDbTextStyleTable
Missing AcDbViewTable
Missing AcDbUCSTable
Missing AcDbViewportTable
Missing AcDbDimStyleTable
Missing AcDbVXTable

使用过的意外数据。

从图形挽回的数据库。

Error 53 (eFilerError) Object discarded
Reading handle ?? object type ??
Error 53 (eFilerError) Object discarded
Reading handle ?? object type ??

按 ENTER 键继续:

最后还是无法修复！但在预览里能看到图形文件！
