Making a spline from three points

[kellenraid]

My model is made of splines that form the rails. The rail-splines are in the x,z-plane. I am importing points that are precise in each sub-plane of the x,z. How can I get a spline to go smoothly through these points? The shape is kinda "U"-shaped with no inflections.

Try Cubic Bezier from Fredo's BZ_Spline set.
