mhaubmann,
Regarding your comment, "...we have a bunch of ES licenses that will not support 3D now...", Are you implying that Mentor is taking away a feature that you already have? If so, I do not think that is the case. In fact I don't even think that is possible. I'm going to assume that you are not on maintenances because Yan clearly stated that, "this new 3D functionality will be available to all PADS flows". Also if you think Allegro & OrCAD share a common database, you are mistaken. OrCAD is still OrCAD even when rebranded as "Allegro Design Entry" and Allegro is still the same layout tool it's always been. They are net list driven just like the PADS standard flow.
