If you ever get the feeling that your massive assemblies are pushing the limits of SolidWorks Performance on your system, check out these tips from CATI, a VAR in the Midwest that’s done a lot of work figuring out the optimal system configuration for large assembly work. They did a presentation at SolidWorks World (SWW) in 2011 that was really in depth and that I still find myself going back to reference (Great job guys!). Here’s a link to their blog posts summarizing their results: http://blog.cati.com/maximizing-solidworks-performance/
And you can even check out the complete presentation on the SWW website. Here’s a link: http://www.solidworks.com/sww/proceedings/proceedings-presentations.htm
Do a search for “performance” in the 2011 proceedings and you can stream the video or download their PowerPoint slides. It’s interesting, but a little heavy on the tech-speak, so here’s a summary of the good stuff.
