Thank you both for the information. It's encouraging to hear that UGS/Siemens' support is of such high quality. We've used PTC and Dassault in the past, and have investigated their options to pay more for "premium" (enterprise or platinum) support. I'm aware that PTC has 2 levels of support...
I'm investigating several PLM software providers, and am curious if anyone knows if UGS/Siemens has a premium maintenance support option, or just one flat support package? I see others like Dassault and PTC have various levels of support at various prices. Thanks!
