AutoCAD 2006 unable to open DWG file created in same version - Drawing file not valid

[smooth shoes]

I have a DWG that was created in version 2006, and when i try to open it in the same version, it says "Drawing file not vaild". I've tried a few different things, but I know I'm missing something simple. Any suggestions?

Thanks in advance

Thanks in advanceAs a work-around, have you tried to insert the drawing into a fresh, empty dwg? If it does work, use the PURGE and AUDIT commands to clean things up. Be sure to purge register applications (RegApps), also.

Or, try opening the DWG with the RECOVER command.

Can you post the file by any chance? May help to take a look at it...

I have tried audit and recover. I don't know what RegApps is. Can you briefly explain? I can't open the drawing at all so how can I purge the Dwg? Thanks for the help.

I am a student and it is not my dwg. I doubt they will let me. I'll check.

Yes, and it says that it is not able to recover selected dwg.

Yes, and it says that it is not able to recover selected dwg.
oh SNAP! That DWG must be toast......... is there a BAK file?

Awesome! I didn't even think of that! The dwg probably was toast, but the .bak file was there. Thanks for the reminder. She says she's gonna buy me a drink for my troubles. Thanks a bunch :)

Thanks for the help.Regapps are things that third-party software tend to put into a dwg file. They tend to muck up the drawing and increase the file size unreasably. For some reason, the PURGE dialog box doesn't get rid of the little buggers, so you have to use the old typed command by typing '-PURGE' at the command prompt.

Meanwhile, a block is just like any other dwg. Sometimes, depending on the initial problem, a drawing can be intserted into a new, blank drawing, then worked on.

Additionally, a bak file is created each time you save a dwg. Unfortunately, if you go a long time between saves, the bak file won't have all the changes.

If its not your drawing, Is there a chance that this file is on a network and was opened by a different user using AutoCAD 2007? The error message is usually a higher version format being opened by a lower AutoCAD version...Just a thought.

More frequently, that message simply means you have a corrupted file, and it is now useless.

Autocad is pretty bad about corrupting files, especially with the newer verticals like Civil-3D. Vanilla isn't so bad, but the newer verticals can be pretty terrible. It's a severe problem with the software that we just seem to have to live with for the time being, and hope Autodesk fixes... :(
