Save and exit corrupts drawing.

This week, many drawings I'm working on are getting corrupted. I save and exit normally and then the drawings cannot be reopened or recovered. I'm using Civil 3D 2019. There's no Civil 3D entities in most of these though and it's even happening on very simple drawings, just randomly. No one else at my office has the issue. Anyone seen this before?

When it corrupts files are there other drawings open?

Any drawing saved with Civil 3D, contains C3D objects, even if they are non-graphical ones. Not necessarily related to your issue, but just an FYI.

Back to the lead story. So you open C3D, you start a new, empty drawing (using NO template), and draw a line, save it, close it, and now you can't reopen it?

It happens randomly, maybe a 1 out of 20 chance that saving will leave a corrupt drawing. I won't know until someone tries to re-open it.

Where are you saving your DWG files to?
And how are you connected to that location?

There is no universal fix for "random": what is the common thread between these 1 in 20 corrupt files, something is, find out, dig deeper, we can't help you with that from way over here.

@EBDBC3D - Is it possible that there is one template file that is being used 5% of the time that is the problem? The template opens fine, but once the drawing is saved - it won't after that?

As @pendean said, 'random' is almost impossible to diagnose and fix. Need to find the common link here.

Test the hardware, especially the RAM. I have seen on RARE occasions where bad RAM causes 'random' things like this to happen.

The drawings use different templates so it's not that. I'll probably re-install AutoCAD, then test hardware if it continues.

Save yourself some time, reinstalling AutoCAD isn't going to solve anything. If anything, log into the PC as a different (and new) Windows user, so that there is a new Windows account and then of course a new ACAD profile when you launch it.

Test this for a while. The vast majority of the time, if the issue is not hardware, it's in the user profile. (I'm not talking about the 'profile' on the Profile tab in Options)
