rubber tipping on spherical surface

[myface]

but if that was the problem it would be enough to project on a floor built for three points, (referring endpoints) a normal axis on the built and passing plane to the central point of the hole/pin which lies on the neutral surface of the spherical cap. In short, keep reference points. the same thing you can do with the ends. Finally decrease the range of the ball and add the shot.

I cannot use the three (vertical) points of reference because theoretically their distance in the projection on the giacent plane decreases to the decrease of the curvature radius, to maintain unchanged the length of the arc that subdues them. by doing tests I approached myself for attempts, approaching, to the final result, but I do not feel sure, I would like to follow for the modeling an exact geometric method or to modify the dowel via sw, setting a decrease of the bending radius however fixing ( keeping unchanged) internal surface and length of the three arches... but with inventor I can't

is why you should ask the question in the inventor section

now it is in the inventor section.. .

That's what happened. I'm happy thank you all.
