You can do a path either as a 3D path or a local path.
These work a little different from each other. the 3D path of course work in 3D and the other not.
But you can use a 3D path in a 2D project as well. I has control points and the local path has benzier tools.
Anyone has some kind of overview when to use the 3D path and when to use the local?
It should be better in general to use Separate Positions for X, Y, and Z for cut-out elements and 3D paths for pegs where you want to animate trajectories. You will want to have the Z axis separated to nudge elements such as a character’s arm behind and in front of its body. On the other hand, if you want to move the whole character, an airplane, etc., on the 3D space, you should use a peg with 3D path so that you’ll be able to edit the motion curve with control points.
sounds like a good way of using it.
