If cost is a big factor, the "10 times more expensive" seems to be a big leap! :O

All owners of V1 can use the beta V2. It is far better. Tools you are missing are there now.

Rhino will have more specialized toolsets to work with. But what are your needs? As a hobbiest are you recieving models from outside vendors and needing to analyze them in different ways?

MoI is a powerful modeler. Not full of 10 trillion different specialized functions though. So the only time I see MoI let anybody down is when they are looking to see if it can "Array-duplicate-curve_twist special-double digit-backflip.....and Michael say's: "Sorry, not yet!".....I may be able to add that in to V3 though...

So I guess if you need to come out of the box doing double dgit backflipping arrayed curves, then you may need to choose rhino. But then again, in Rhino you will need to buy the "Add-On" that does that, so there goes more money! THe cost of those add-ons is fairly large.

MoI's future is Bright. It would not be a poor investment.

Plus of all....The guy that is responding to you in here "Wrote Rhino".
