8 Adding More layers

now take the layer two surface, and skin that to all three controls (start, middle and end). We continue to have multiple options on how this rig ends up. We could end it right here and simply wrap the original surface to layer two. However, to get a smoother result, we could use the rebuild surface option to give us a cubic surface to wrap to, rather than a linear one. Use the Edit nurbs>rebuild surface menu with the layer two surface selected. Make sure that Keep original is checked. now you should have a little play around with the controls so that you can see how the surfaces are affected. you can see the rebuilt surface with history from the layer two surface. By making the rebuilt surface cubic in the U direction, the result is a smoother surface. Here’s what it would look like if we wrapped the original surface to the newly rebuilt, cubic layer two surface.
