greetings! I have a great workstation using a Quatro video card, 12 gigs of memory. However when I create linear patterns from extrudes and fillet, it runs really slow and takes forever to the see the results. Picture a plate with small symbols patterns up and down on a 5 1/2 by 5 1/2 plate which is Two sided. I added more memory (12 gigs) and video card has 4 gigs. Still running slow. I would love to find out why its running slow.
