Tutorial: How to create a (soccer) football like the never-before-seen Brazuca!
Created in PTC Creo 2.0. You should have some experience with surface modelling for this one.
The Adidas Brazuca is the official match ball of the 2014 FIFA World Cup which will be held in Brazil. Interesting design which seems to have been built up of six panels, so why not create a CAD model to puzzle-out how this works!

not a bad tutorial how ever
its not accurate in terms of seams overlap and correct pattern seam compression
a draft of TWO seams that is also requirement and fundamental to actually manufacturing the parts in a compression laminating sphere
what we want to see is a sweep of the two sided draft angles as the ascending draft is not equal to the descending draft along the larger surfaces - this is not clear until you analyze the draft angles as the sweep revolves alone the curves. having modeled 12 different soccer balls since 1972 the clear challenges is not only in laminating a tiled cut in the form of an X but to make the revolved draft angle adjust in according to the ascending material at the manufacturer's Dye.
note in the images below of modeled versus manufactured actual product that the seams are indeed NON uniform over the surface
I decided to create this.
I used the Sweep Tool in Autocad to get it to look right.
