UNDO file size

7013 Views, 14 Replies

Constantly getting box that says "Warning! The undo file length is xxxxx bytes. Undo will be automatically disabled at 1750000000 bytes to prevent overflow. You can clear the undo file by turning undo off and then on again via the undo command."  This is very aggravating.

Use UNDO-CONTROL-NONE, then UNDO-CONTROL-ALL, list in Taskbar UNDO empties and it works again for a short while, but then I cannot undo past this point.

This box popped up once during a command and caused Civil 3D to lock up, causing me to lose work.

 

Web search does not find much help.  Does anyone know a fix, how to address this, or how to increase the file length so I do not get this message?

Are you short of space on the drive the temp files are stored on? Have you tried clearing the temp folder.

I had cleared the temp folder under my user name (accessed by typing %TEMP% in the windows command line), and it did not help.  However, I just found that my temporary drawing location is set to C:\TEMP.  I just cleared all files from that folder.  Do you think this will help?

BTW, Windows 7 64-bit w/ Civil 3D 2013.

It's the Autosave path that holds the AutoCAD temp file location.as.PNG

 

That may be C:\Temp or elsewhere. Don't know if it will help until you try it. It's the first thing to try though.

Actually I do not believe I have gotten this error a single time since I cleared that Temp folder.  However, I have not had to work any more in the drawing that was most troublesome for me with this error.  Presuming the occurrence of this error is not somehow related to being in a certain drawing, I may have it fixed.  I will post back if it does happen again.

I am having the same error

 

Clearing the Temp Files will fix the problem untill the Temp file again fills up and you will see the saim error

when that happens just save your file close cad and clear the temp filder again

 

if i find a better solution i will post it

 

only happens in large files in my experiance

 

regards

I am getting this error on many machines in my office now (8 that I know of).  A custom temp folder is set and has been kept clean.  The undo file size is out of control though.  900+ mb and I can't see why.  The task being done are not complicated and the drawings are not huge.  Definately big drawings are worse, getting undo overflows several times a day, but many other smaller drawings have the same issue.  The undo command also doesnt seem to group commands properly even though it is set to do so in options and you have to undo many times to go back only a few steps.  Maybe this is part of the reason the undo file gets so insanely large so fast?  These are all the same types of drawing we used in civil 2011 and never had any issues with undoing or undo overflows.  Our work flows have not changed but the software is increadibly unstable in this regard.  The worst part is that the notification that your undo file is getting large often hangs the drawing, so you are forced to shut down Autocad.

 

Any advice beyond keeping the temp file clean?  The active temp file seems to be the issue, not all the other files in the directory.

Actually, that only specifies the location for autosave files.

There is an entry a bit further down for "temporary drawing file location" (also equals the r/o sysvar TEMPPREFIX)
