Audit Bad Files

[Detsenira]

Hi to all:

How do you think I can removed or fixed a ($Audit-Bad-Block). Every time I open the insert block, my computer slows down and there is a fatal error that follows. I have no Idea how it happened. Sounds like there is a virus that infects the file. Is any one experienced the same and have an Idea how to resolve the issue.

Immediate response is highly appreciated.

Thanks,

Ted (Auto-CAD-2007 user).

I'm guessing that you're seeing that block name in your block list while using the Insert command?
Try using the Purge command. That might actually get rid of that "block", which was created during an Audit from something invalid.

I agree with Sue. I've had this problem too, but minus the crash. If the file keeps crashing on you, try opening it with RECOVER.

Yes, just notice bad block on the list when I tried to use insert block and open design center causes the computer to freeze. I don’t know how it happened and how to delete mentioned bad files.

I did tried purge but notice that particular bad files can’t be purge. I tried to run audit but it get stuck somewhere along the way that might possibly causes by those particular bad files. I tried to open that particular files using recover same problem occurred maybe because the bad files already exist prior to saving it.

Just to keep my project going. What I did is to copy paste all the entities into newly created files and notice subject bad file was gone.

Now my question is how it happened and how to deal with it without deleting the entire files? Do you think the file was infected of any kind of virus or that particular file was corrupted and not recovered totally?

Thanks again,

Ted

We've found this is more or less of a problem depending on which version of AutoCAD you use. In the articles on Autodesk's site, you will always find this referred to in the passive voice - "the file(s) became corrupted...," not "AutoCAD corrupted the file...", as if it were some act of God. Nevertheless, AutoCAD 2002, for example, was so prone to choking on its own data that they seem to have worked on the problem, as we've found AutoCAD 2006 to be a lot more robust (but there are still occasional burps). So if you're using an older version, upgrading may help. (Although 2006 is itself already an older version - I don't know how stable 2007 and 2008 are.)

As for what actions specifically cause file corruption, there isn't much information available. However, in our experience, 2002 seemed to have a lot of problems surrounding the creation of hatches, and all versions seem to get a little (or a lot) cranky when asked to handle objects created in non-AutoCAD ARX applications. Sometimes these are called "third party" applications, but more often than not they are the vertical applications offered by Autodesk itself, so there really isn't a third party involved.

There is also a standard set of approaches to fixing corrupted files:

- AUDIT command
- RECOVER command
- insert the file into a blank drawing
- copy and paste the objects you want into a blank drawing (which you did)
- try opening and saving the file in another application (i.e., Intellicad) that handles the .dwg format
- send the file to your dealer and see if they (or Autodesk) can do anything with it

Hope this helps,

Did you try using quick select to select all the bad blocks (by name) and deleting them? (Then purge). I find that it's much easier than copying everything out.
