You get the individual layers to send to the machine to reproduce by slicing or contouring the 3D geometry at the interval that the Z increments. It's mathematically much easier to "connect the dots" by finding the two points that a triangle intersects a plane than to find the equation of a line that intersects a NURB surface to a predetermined error. AND the lines are guaranteed to connect on the other side of a closed manifold polygon object - only within twice the error at the edges of adjacent NURB patches.
