My computer just shut down without warning, I lost my revision, as I know autocad save temporary files automatically. I might be able to get my revision back by recovering from autosave file.
Any help will be appreciate, thanks in advance.
How to recover .dwg files, the answer might be here- http://www.filerepairforum.com/forum/cad-tools/cad-tools-aa/dwg/444-%E2%80%8Berror-cannot-open-file-open-cad-drawing-dwg-format
Another method which I usually attempt before looking for .bak files is to open a blank drawing and insert the corrupt one into it as a block. This often works and it is then a simple case of exploding the block, running the Audit command and saving the drawing.
Failing this, as others have said, try opening the drawing on another PC or try to open it with any other program capable of opening a dwg file.
