So we can see from the Wikipedia page the next new model of Fooball :)

Hi thankyou Michael for the ball there is a lot technics here and I'm new to it, I will show it to my son later today
his mother is calling me stupid I was banging my head on the wall last night and if he doesn't like it I will take him to the river
thankyou again

Hi Hamid here is a way how to do it:
on top view make triangle with polygone tool ,
one small one add pts to it
make hexagone ,
snap the cpts to hexagone end points
make Z blue axe
rotate (make copy) triangle and pink shape,snap to Z blue axe




make sphere in the center RED PT (red point is the int off the blue axes )
Project the pink shape to sphere ( closeste pts )
circular array 3 on Z axes
make red lines and project to closeste


draw circle on shpere and project closest ,circular array.
--------------------------------------------------------
new shape easy to do with 3 sided pyramid ( Tetrahedron ) and sphere
1 intersect ,draw yellow polyline project closeset
2 chamfer the pyramid project closeset edges on sphere . intersect the sphere and the pyramid

Hi Lyes thank you for your help my son is happy with Michael ball , its hard for me all that geometry in 3d ,
he like MOI3D and is learning it.
thanks all.
