Hi Billa, you're welcome! So it is very easy for someone with a background in poly modeling to approach it the way you were doing it initially. In poly modeling you're usually avoiding booleans entirely while in NURBS modeling you want to have booleans as the main preferred strategy. Part of that is trying to focus on an initial larger extended shape.

If you find yourself doing a whole lot of filling in pieces with loft or network that can be an indicator that you're not going in the optimal path for NURBS modeling.
