I've been using Solidworks for 4 years now, but only on my own projects and assemblies internal to the company. We have a standalone computer, no PDM, and I have just gotten an assembly made by someone else. It has about 1100 components stuffed into sub-assemblies of the main assembly. I'm wondering if there is a workflow as to how you go about trying to understand the design intent of the person? What all the mates are and how one part is referenced by other parts? I tried to change one hole size and found so many errors in the assembly that I quit the part.
