Yes, General Motors is definitely using UGNX 9 with Teamcenter 10.
They should have gone to UGNX 10 as they (Siemens) now has "Line Designer."
They could then phase out "FactoryCad" once and for all. But they did not think clearly on this. Still far too many people NOT knowing
what the other is doing for whats best for GM. Picture a tangled cobweb - thats the decision makers at GM to this day. So sad.
