UNHANDLED ERROR ECC3BE52H

[jerry.wms]

I am working on a project using project navigator in 2012 MEP. I detached an xref from one drwing. All the sudden i get UNHANDLED ERROR ECC3BE52H.  I reported the error to autodesk.  They instructed me to install service pack 2 and I did. Now, I have multiple drawings in this project that will not even open, i just get the unhandled error.  I recovered one drawing, now it won't even begin to open, it won't do anything at all.  Some drawings in the project are just fine.

The project could have been corrupted.  The project support files are xml files which are fancy text files.  The apj is what typically gets corrupted.  Close AutoCAD MEP.  Use Windows Explorer to copy the whole project folder to clipboard, then paste it in some other folder, you are essentially moving the project.  From the new location, find the apj file and double-click it.  That launches AutoCAD MEP and it opens to this project.  In trhe process, it notices the project has been moved and it asks if you want to repath the xrefs.  Say YES.  This not only repaths the xrefs, but it rebuilds the apj file from scratch thus removing any corruption.  Most people hesitate at moving the project.  So move it back and repath one more time.  Project gets back to it's original location and eliminates the corruption.

Hope this helps,

Joshua

Joshua,

Well, I did as you suggested. The first time I opened a drawing it showed "UNHANDLED ERROR E9EC0F777H".  I tried to open again and the drawing looks like the attached.  I think a whole lot of time just went down the toilet.

Joshua,

What causes the files to get corrupt?  This is the 2nd project I have lost in a year.  The first, Autodesk blamed on a possible corrupt file from the architect. But, it waited until I was almost complete with the project to wipe it out. I did a complete un-install and re-install of the program then as suggested. What can i do to help prevent this? I really don't read alot about any one else loosing projects.There is too much time lost and not enough time to make it up.

Have you tried an Audit or a Recover on the file?  Would you post the file here so we can help?  Is there any 3rd party applications like Quickpen, CADDUCT, EastCoast CAD where we may may need object enablers to view this?

To your latest question about file corruption.  Files and software are just bytes of data 0's and 1's.  Going from memory here but a byte is eight 0's or 1's.  So a kilobyte is 1,000.  Times 8, that's 8,000 0's and 1's.  1-Megabyte is 1,000 times more, and a gigabyte is another 1,000 times more.  A decent drawing file these days ranges from 5 MB to 100MB.  That's 8,000,000 * (5 to 100) of the 0's and 1's.  Then you have a hard drive spinning fast and with ever increasing density storage of data.  Ie. The data is stored in a smaller area.  CPU's are faster processing the 0's and 1's at Giga-hertz speeds.  Toss in multi-tasking and losses from wires.  Send your data across network cables.  Point is that eventually a 0 gets mistaken for a 1, they get flipped.  Flip it in the wrong spot and the computer can no longer understand the message.  It's garbage and the file gets corrupted.  Can our software corrupt a file?  It's 0's and 1's like all other software.  Here's my personal way of discerning if a file corruption is normal.  A corrupt file once a month is bound to happen.  Once a week is too frequent.  Start checking for loose cables that may be dropping data.  Once a day, it's likely to be software driven.  Try identifying some common steps/tasks that lead to the crash.  Anything less frequent than once a month is just random occurrences.

That said, if you backup your files daily off a server and keep at least 6-months of storage then the loss of work is minimized.

The above is my humble opinion and based on my experience.  Hope this helps,

Joshua

Joshua,

We do save and back up on a server.  I am checking to see how often it backs up and how long it stores for.  The dwg files are too big to attach but you can follow the link below to download.  I do not use any 3rd party applications. Yes i have tried to recover, and I have tried to audit the dwgs that will open.

10-69-1ST-FLR-DUCT.dwg; 10-69-1ST-FLR-EQPMT.dwg; 10-69-1ST-FLR-DRN-HYDRONIC-PIPING.dwg; 10-69-1ST-FL...

I am crossing my fingers that there is a previous back up found on the server.

[Joshua.Benoist]

It appears that just two files (10-69-1ST-FLR-EQPMT.dwg and 10-69-1ST-FLR-DUCT.dwg) were corrupted.  The other files reference in one of these two files.  So they crash.  We recovered both and found 30,600 errors.  Files appear fixed now but did lose information.  The mvblocks were moved to a layer: $AUDIT_BAD_LAYER1 and may have lost their geometry.  Once these files were recovered, the other files opened fine.  See attached.

Joshua,

The computer people came out and were able to find a back up. We are a  small company and I was not aware that our server is backed up regularly. I opened the dwg's  one at a time and audited them. there was only one dwg with 46 errors. Dwg is repaired I only lost a few days work.  Thanks for your help.
