I use AutoCad 2004, and am running into the same issues.

For smaller files, this was not a problem, and only took a second or so for a regen, which I have on a keyboard shortcut key.

For my current project, I have perhaps 100 drawings in one file, which is about 8MB, and the regens have become longer than I would like, along the lines of perhaps 20 seconds.

People have said "Don't put all your drawings in one file", but the efficiency of cut-and-paste, and the quick access to all areas of the design make it the only efficient way to do the project.

I am having to purchase a new computer, with hopes that the problem will be minimized.

I bought an HP desktop, 32GB ram, 6GB ram on the video card.

I hope this computer works, since I have a lot of money riding on this project.

One thing I have found that helps is running the purge command repeatedly until the file is cleaned up.

I have found that this can reduce a file size from 10 MB to perhaps 6 MB.
