"drawing file not valid"

[pgw]

Hi, I did not find any answer in any earlier treads, so:

I have autocad 2002. Now I have a file that says "drawing file not valid" when I am trying to open it. Autocad starts, but the files does not open. It is only worked on in this 2002, never saved by someone else etc, it is the same file that worked well in beginning of september.

Any idea what to do, how to recover it?

Try using the RECOVER command.

Hello,

I tried but it did not work... any other idea?

Download DWG TrueView and see if you can open the drawing with it. It's free at the AutoDesk website.

In similar circumstances, I would do a couple of things.

I would open the file with a text editor (NotePad or WordPad) and see whether the first line was AC1015.

If it was not, then I would convert it with Dwg TrueView.
If it was, I would try starting a new drawing from scratch, and then insert the troublesome drawing as a block and explode.

If neither of those worked, I would come back to CADTutor for further advice.

Hello,

thanks for both your advices. I could not open the file with Trueview though. Said the same thing "drawing file not valid".

Any other bright ideas?

What was the result from my other two suggestions?

Thanks for the advice, it said the same thing though, "drawing file not valid" or similar..

I did not see something like AC1015 when I openend the file with wordpad. Should it be in the very beginning?
I tried to open it with DWg trueview but it said that the file was not valid.
I also tried to put in the file into an other document, a cad file, i did not manage to put it in there.

AC1015 should be the very first characters of the first line when opened in WordPad. The rest of the file should be characters only understandable to the computer.
