I’m trying to learn the basics of rigging/constraint driven animation. For this I’m trying to animate a simple radial piston engine.
I used these tutorials as a start:
But I have trouble setting up some of the constraints…
(Please see attached sketch of a very simplified mechanism)
The Bone is a placeholder for a piston rod. It’s base (1) is attached to the circle, rotating around the center ©. So far so good.
Now I want the top of the bone (2) to move only along the direction of the second linear path §, while maintaining it’s length (the curve only defines a direction not the extends of the motion).
I tried “everything” Point and Aim Constraints, motion path etc, but can’t get it to work.
Any help is greatly appreciated.
