We have an issue where is takes 15-45 minutes to open up drawings in SW07 Sp1.1. We run off a 100Mb network and the way things are we do not have an option of running local. But when we are opening drawings you can watch the network activity and the blue progress bar on the botton of the SW screen and it just flies loading all the parts. Then it just bogs down from there, And when it does this you can look at the task manager and see the SolidWorks is not responsing and a program called Draw Compare is running. My question is what is Draw Compare and why does it seem to slow everything down.
