We are encountering this same problem with several of my users. We do not understand why we cannot save the file. It is a random problem that occurs every once in a while. Any solutions yet?
I even opened a ticket with Autodesk. They offered the usual advice and even suggested some things that our IT guy had no clue what they were talking about. We still have this issue. It only started with us when we got off our Novell network and onto a Windows network. About half of us are using Win 7 64 bit. Most are on some Autodesk 2010 product, but some are on 2011. Its happening to most of us occassionally. Most of the time we can just hit the space bar to re-issue the qsave command and it saves. Sometimes it just plain ol' won't save.
Okay, here's what's worked for us... at least for the past 2 hours.
After reading a few threads about Indexing causing some problems, I went to the folder that a user with this problem was working in and turned off indexing for the whole folder. See attachment.
I had the same problem but i later realived that the drive on which the drawing was was full. I was able to save after freeing some space.
NOT fixed in 2011, I've had drawings that have this issue, then i purge audit and they save ok, and a few minutes later same issue, I leave autosave on so that at least i will know if there is an issue (pop up appears when trying to autosave) as often when I go to audit it crashes. Mainly happens when working with corridors or corridor surfaces
The indexing suggestion is an interesting one, I have a similar issue with realtime anti virus but not sure how it would explain a continual problem with a drawing.
Does anyone know the core reason for the error??
It would appear that there is a corruption in the file potentially caused by;
deletion of refference objects, - Drawing doesn't know where object is thus confused database; easy fix
having RD on your system - I don't understnad this one really but aparently it's fixed??
trying to write to a disk that is full or in use at time of write, - I'm guessing while transferring data from ram to disk it is possible to suddenly loose continuity of the file if there is a read/write issue, not sure how this ties in with the .tmp files?
So audit works to let you save once or twice (without seeming to fix any errors) so why does the issue reoccur in the same drawing?
"... then i purge audit and they save ok, and a few minutes later same issue..."
So the problem either is never fixed, or is re-established through a series of commands or functions: WBLOCK and INSERT into a working template file to see if the problem goes away.
AECTOACAD command is great at removing AEC content that are not native to your plain AutoCAD version.
And what is a corridor surface? I take it you're not using plain AutoCAD 2011 where you are posting? Or are you, but the file is from a vertical?
