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 (Gold and Platinum) and Dassault has 3 levels (Secure, Advantage, and Enterprise). Any idea if UGS/Siemens offers the same, or just one catch-all package?
