Deform mesh from deforming Spline



I’m really trying to wrap my head around C4D’s workflow, please excuse my beginner questions… :blush:

How would I use a Spline with a Displacement on it, to deform an object? I don’t know how to use the Spline to drive the motion of the Mesh.

attached is a screengrab of the Spline inside the mesh.

Any ideas?

Thanks again
