Soccer Ball

I made this model of a soccer ball a while back, but haven't gotten around to uploading it until now. It was pretty challenging to figure out how to make at first, but I'm quite satisfied with the results.

The method which ended up working was to use a 3D sketch in conjunction with a loft to create a hexagonal pyramid slightly larger than than the radius of the ball. 

Intersecting this solid with a hollow sphere formed by revolution resulted in the desired hexagonal patch. A similar method was used to create the pentagonal patch in a different part file.

The patches were then assembled into the final product with the help of some construction geometry.
