We have SolidWorks premium, Splidworks PDM Professional, and an active subscription service.  Are these all additional products, or do some/all of these optional items fall under the umbrella of SolidWorks Premium?  And if they do should I just enter the SolidWorks serial number to gain access to them?  What about Visualize, just use the SolidWorks serial number?  Thanks for your help!
