The best way for me to translate UG file to an other rendering software is to use VRML format (as you can set the accuracy of the model you want to read).
I worked fine with 3D max for example.
But the new NX3 provides configurations for assembly and I've heard that it helps to animate...
Yes, UG until NX2 doesn't support tif plotting onto a drawing. (this new function appears as unuasuable until they change the PQMGR to windows printer)
I've hear the NX3 shows shaded preview while positioning a new view.... but nothing about plotting yet.
