Big DWGs slowing down CAD
Big DWGs slowing down CAD
(OP)
I allocated 1.5GB min to 3.0GB max to virtual memory and have a decently fast computer (or so I thought). BUT when I open this 64 MB drawing in CAD with about 25 tabs, everything gets really slow. What is 1GB of RAM good for if I can't ust it for large drawings? How can I fix this problem?
Pentium 4 CPU 2.80GHz & 1GB RAM
Running WinXP Pro SP2
74 GB Harddrive half of which is free space

I just don't understand why that slows things down so much when I have a gig of RAM. . . I really need to ask a computer tech guy this question don't I?

Good Luck

or you could try using partial open to open just what you need to work on and see if that makes any difference

Purge the hell out of it and delete any stray non referenced objects in the drawing (like blank attributes that have been disasociated with exploded blocks)
Turn on all the layers you need then do this to erase all unreferenced objects. - Erase - All - Deselect all objects on screen (Shift+drag window around all objects).
Also delete all your layer filters except the ones you need.
This should bring the file size down a good bit.
Also the biggest bottleneck in your PC might actually be your graphics card, You need a really good one to handle a 64MB drawing.
What kind of drawing is it & what kind of graphics card have you?, just out of interest.

Paddymac: The file is a civil drawing with a number of different layouts. These things can get big pretty quickly. The project is to design a reservoir, pump stations, and other water diversion structures etc for a square mile plot of land. We probably have a gigabyte worth of drawings on all of it. One of the drawings got up to over 100MB at one point. . .
Graphics card: generic Intel 82865G Graphics Controller. Max of 64MB of graphics memory.

It shouldn't be to hard to justify the cost to your boss. You might be able to get your IT supplier to loan you a card for trial purposes for a few days to see the difference.
