binding part to a path

[LucaOt]

Hello everyone, I have a problem I can't solve. I press that I am new in the inventor world so I apologize early for the possible banality of the question. I have to bind a part to a path so that I can drag it with the mouse, in the environment together. attached I made a temple and a sphere. If I try to bind to the straight part of the solo, it follows only that ignoring the arc. if constraint to the arc, the sphere is placed on the axis of the same but not along the path. Can you help me? Thank you.
