Problems with Errors

Lately I've been having some major problems with drawings. I draw for a while and all of sudden Autocad freezes up. I'm using AutoCAD 2006 at work. I run the Audit command and it says I have a lot of errors in the drawing. One of them came up 180 or so but it just keeps creating errors. Does anyone know what this could be from or how to fix it without starting the drawing over?

Sounds like a corrupted drawing. Audit usually works but not always.

You can experiemnt with copies of the drawing, purging and erasing and detaching everything you can safely duplicate later. The idea is that possibly some dependant item, like a suspicious block, or naming issues are being caused by a single element, and when you remove it step by step, and then re-open and check fro the same erros. Note also where the errors are coming from, because again, sometimes it's one bad link in the database that is causing all the problems, and you may have to go through and dump and dissect to locate it. You may aslo try stepping backwards in versions to locate a release culprit of some sort. If you have error codes also search ADN knowledge base and the web in general, as sometimes a culprit gets identified by a number of users. It seems the more complex a drawing, the more chance of strange errors, and again, it's often one thing, like an old huge block, or a layer with zombies, or something, so clean it out a step at a time. Step back in versions, look at the errors, if they are thrown from a single source, etc.
