When I purchased D-7 Pro, I deleted my X3D-6 thinking all it does would be in the flagship program - bad move. I guess there are ways to do at least some of the things that 3D does using animation and some of the other parts of D-7 but 3D is so much quicker and easier to use.

I can find no way to re-download X3D-6, only -7, but have contacted support to see if they can send me a link - so is there much difference between -6 and -7? If so, I would upgrade to -7. With the time since 3D has been upgraded, I would think there are a lot of new "goodies". - jb
