Detaching Nurbs

In this snapshot, you can see three different NURB surfaces. There is the top 2/3 of a sphere, and the bottom 1/3 of the same sphere, and then there is another shape that looks kind of like an egg. This snapshot demonstrates the ability to "Detach" a NURB object with the two different parts of the same sphere. It also demonstrates the ability to "Attach Surfaces" with the object on the left, which is the result of attaching the two parts of the sphere back together, and then translating the top part of the sphere up. The newly created attached object changes its shape because it is still live and history is still on.
