Creating A Pattern For A Sphere In Rhino

So…

I've downloaded/installed my 90-day evaluation copy of Rhino 5 for the Mac. (Playing around to see if I really want to purchase it, MIGHT be able to qualify for the student discount through my apprenticeship. PLEASE OH PLEASE!)

Anyway, I've started playing around a bit, and naturally have tried to do what apparently is a non-trivial task: Make a sphere, and then create a 2D pattern that will build up into same.

Looking for something like the attached picture (Which, BTW, is from the page explaining what UnrollSrf can/cannot do).

So far, I've learned that the UnrollSrf command will not work, due to the sphere's surface curving in more than one direction.

Various Google searches have pointed me towards the "Squish" command, but results have been… Not what I expected/am looking to achieve. More of a bug splat, actually…

I'm beginning to understand developable and non-developable surfaces, but that's as far as I've gone.

Can anyone help (or at least point me in the direction of a good tutorial on this)?

Thanks!
