Compute the curve(s) on surface given a curve to project and the surface to project onto. If useNormal is true, the normals of the surface are used for the direction of projection. Otherwise, if useNormal is false then the project direction can be specified by the direction input. Note that the result of this operation is a 2 dimensional curve.
