I have tested 2.1 and I am in the process of installing it on all our machines. 2.1 was definitely an improvement on 1.0. Drawing performance is as it should be, which is much improved over previous versions of SolidWorks thanks to the lightweight sub-assemblies and drawings and somewhat to the draft view quality option. I have noticed some issues with the conversion wizard failing on some assembly drawings, though. When I open these failed drawing files and try to save, they crash (un handled error). I have spoken to my VAR about it they said they have heard that from several of their customers. They are trying to nail it down and then log a complaint. The solution for me was to open the assembly first, set all components to fully resolved, force rebuild (Cntrl Q), save, and then open the assembly drawing. At this point I was able to save and then close and reopen the drawing without crashing. Other than those few files, 2004 seems to be running much better. Still, it almost seems like SP 1.0 was a terrible SP and should not have been released. Some might argue others should not have been released either, but thats the reason why I waited and tested here before rolling out to the rest of the company. However, a large cost was involved for my company as it was my time being eaten up instead of SolidWorks releasing some more stable versions in the beginning. I agree, that anyone should test before rolling out to a larger audience, but it would be nice if the confidence level in quality service packs could be higher. Thanks for all who added to this original post. Your help and thoughts on 2.1 was appreciated.
