Notice the end result with the very smoothly and organically rotated midsection of the vase. This is the power of FFD.

Chris once stated on the forums if "anyone actually used this script for anything useful yet". Well Chris, now you know it is. A very powerful and very useful tool indeed!

As said before, the control grid CP's can be moved, rotated and manipulated in any way known in SketchUp and FFD will apply whatever that action is, to the mesh, and updates the scene after you finish the operation.
