Hi Hamid, that's a pretty difficult model to try and start with - it's not really an ideal candidate model for the NURBS modeling techniques that MoI uses.

I'd recommend learning MoI by making something that is more well defined by 2D plan curves. NURBS modeling tends to work the easiest with models that can use 2D curves to define them and use as profile to cut holes, etc.... The ball model you want to create does not really fit in that category.

You could still try to model it in MoI, but it will use a variety of much more advanced tools (like doing a lot of projection of curves on to a sphere) and won't really be using the easier and faster areas of MoI's modeling tools.

Or do you possibly have any kind of 2D plan drawing available of some of the elements of the Jabulani ball, like some of the patterns arranged in a 2D drawing instead of only the 3D image of it? Those could possibly help.
