Re: Audit Bad Files
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,
