Hey guys, I am using Civil 3D 2011, and the last 2 days I have been running into this issue. I tried google, and the most recent item google brought up was from May 2011, so I am coming here.
I am trying to import a tab from another drawing, and it does not matter which tab or what drawing, I am getting this issue.
Does anyone have any ideas?
This is the only work around I have found for that problem. Save your drawing, type UNDO, enter, type Control (just C), set your undo option to none. Import your tab (or whatever, this may take a while). Save drawing exit Autocad. Make sure your undo is turned back on and continue working.
Make sure Windows Explorer is configured to show System & Hidden files. Then in the address bar enter %TEMP%
Yup, all of my temp files are gone. Where exactly does ACAD put the undo file? I read somewhere that it was limited to 256 MB or so, is this correct?
I would assume it is stored in memeory. I am not positive about that. And I do think you are correct about the size of the undo. I do know that when I get that error message, I set the undo to none, perform whatever operation then just turn the undo back on. I haven't had any other problems doing this.
The Undo files should be wherever the Temp dwg location is set in options.
You can also type TEMPPREFIX to check the location.
I believe they are in this format.
BTW If your in Civil 3D your temp folder should not be empty. This could also be caused by a rights issue. If you IT suddenly restricted your rights to the folder I believe that it could cause the message you get. Possibly it would can not write message.
Well. That didn't make any sense. It is causing a write error.
