Re: ULTIMATE CHALLENGE

OK so i really don't want to do this because i know that it will take some time but i came up with a "simple" way of doing it.



If you create a sphere in the cad of your choice, then make a datum plane tangent to the sphere. make a new sketch of the pentagon or hexagon shape on the centerline of the sphere and extrude the outer portion away, you will be left with a pentagon/hexagon rod with compound curves on the ends. extrude away so you are left with a pent/hex block with 1 curve edge and 1 flat. If you then chamfer the edges to the proper degree (not sure what it is), and fillet the corners of the part you will have a building block for the ball. You will need to make both a pent and a hex part. Create a new assembly, and assemble the pieces together......done deal.

now that i typed that out i may try it when i have a few seconds. The only choice now is the software (pro-e, inventor, or solid works).
