ACAD 2007 Question

We've just recently upgraded from ACAD 2005 to ACAD 2007. I use ACAD for manufacturing design and plant layouts. When working with a fairly large layout drawing of a plant that is around 2,000,000 square feet in size. There are a lot of machines drawn in the layout and when trying to zoom, pan or just move an object the PC just drags and hangs up, it appears that the drawing is maybe regenerating a lot?
I went under "Options" then the "Selection" tab, for "Selection Preview" I unchecked "When no command is active", and on the same tab under "Visual Effect Settings" I'm selecting only "Dash" in stead of both. This helped a little but I'm sure there must be some settings that allow a large drawing to be smoother and more manageable. The PC is actually a laptop, an IBM Thinkpad T42P with 1Gb of RAM. Should be plenty to run ACAD.
Any suggestions as to what other settings that are in ACAD 2007 that will help?
Thanks, Brian

Is your hard drive light blinking during the pans and zooms? If so, then you need more memory. Remember that you just upgraded to a bigger memory footprint version of Autocad, and since the system needs more memory for the software, less is available for the file, so more is being placed in Virtual Memory (translates to slower hard drive pretending to be memory)

Hi
I belive that Autodesk reckon about 2GB Ram for ACAD 2007 I would probably add another 1GB. Also I think a decent amount of video memory and I would think a 128MB card as a min - probably 256MB or above.
Good luck
Paul
