rolling ball on floor

[vingal]

good evening, I have a problem in the kinematics to roll the ball on a rectangular plane, I traccio the median line of the base, for the ball instead I define the contact curve with the line and imposed the rolling joint, then imposed the surface contact between the plane and the point of the ball, set as fixed part the plan, but the mechanism does not simulate. I think the problem is due to the fact that I didn't put a crawling joint, the problem is that I don't know which curves to put it, I would thank you if you could help me, thank you.

Hi.

I don't know kinematics, but I would try like this:

put a point in the center of the sphere
make a curve offset from the top, equal to the ball radius
put a link between the point and the curve

Let me know.

Hi.

the problem is that in kinematics for the rolling constraint you can not set an offset and the two curves must be in contact.

Can't anyone give me an answer? ? ? ?

try to put some image of what you are doing and errors or requests that the system gives you in doing the various operations
