Michael:

Most of the things that you listed are things that I do not need Rhino for. I have Rhino, SolidWorks, SpaceClaim and Alibre Expert. I prefer MoI as I don't need detail drawings, simple FEA, CAM paths, etc. Rhino has always got me excited so it always sticks in my head as a needed tool but I am sure that beyond a few specific surface tools that I don't even know how to use, a solid MoI user can probably create most anything a strong Rhino user can create.

I think the surfacing items that you stated that MoI is missing now there are probably many work-arounds and this forum seems to have some awesome knowledge behind it.

I think I will stick with Rhino 4 and skip the updated.

Thank you and thanks to all that replied!

Now I get to blow that upgrade money on something else, right? Don't tell my wife.
