Yeah, in Maya you make the object ‘live’ and draw your curve onto the surface. From that point the curve will move with that surface. For example a motion path for a sail boat in the ocean dipping and bobbing with the waves as it moves along the path.
In C4D you can project a curve. But I’m not up to snuff so the genius’ here will have some good ideas. I know with a little xpresso you can lock the positions of points to other points.
