Hey, guys.
I'm doing a cinematic test.
I want the pink piece, moving in x, rotate the yellow wheel.
the mechanism based on the principle of the sloped plane.
the yellow component rotates because for the perpendicular component of the tilted plane.

If anyone can help me.
I also attach files made with r20.

Hi:
 
the solution is line/point (the edge of the yellow/spigol piece of the pink piece), but the mechanism does not work because turning the two planes no longer coincide and happens interconnection. the pink piece should be at least a cone, if not a ball.

Hello, Marco, thank you for the answer.
I don't understand, the mechanism doesn't work in the casket or does it?
Can you take the attached catproduct and show me where to apply the line/point?

Thanks:-)
 
Your mechanism doesn't work in reality.
the planes of the two pieces of furniture are coincident, but when one wheel and the other translating these two floors unleashed. There is no common point of contact.
if the translating part is spherical or conical then the contact point between the two elements is controllable.
the simplest is the conical that resolves with a point/surface joint.
more complicated is with the ball. for this I will send you back to my post-Ciapedia where a cam follower is explained, and this would be the same case.
Anyway, I'll tie you the working file with the cone.

It's okay, but I just need a small rotation of the yellow wheel.
I tried to make a little test.
it seems he from the attached file you can understand what I mean.

Hi.
 
I understand. with catia you can do what you want, you tie a point to a surface and solve the problem of seeing an animation.
However, the movement is not the real point of contact, really, it would move from the position you imposed, not to have interconnection.
In your case, you have a non-real movement with computation.
