Hi xrok1, yes it will definitely be a pretty big project in any system.

Some solid modeling systems like SolidWorks are really really focused on doing everything driven by 2D profile curves only - I'm not sure that they even make it possible to drag individual points of a sketch curve up to different levels in Z to create a 3D swooping curve like you can in MoI or Rhino.

So I think that MoI is likely to be a step forward from a very Mechanical CAD type program for doing this design.

But really once you are looking at a more sculpting type of procedure where you may want to make surfaces with subtle adjustments in them with some regions that kind of "bump" in or out, then that is really when the tools in a subdivision surface modeler do a better job - it is the type of thing that they are really focused on doing. MoI is just not as focused on this type of thing at this time.

If you do want to pursue it more in MoI, then another possible direction would be to model a base surface of the grip without the finger grooves in it, and then try to place the grooves in as separate parts later on, that may make it easier to create the basic form of the grip.

It's going to be a lot of work though...
