another related question:
I started rebuilding this nurbs head according to the Gnomon video-Organic Modeling again...just to see if I missed something. I believe I explained before that we start with a Nurbs cylinder with no caps and then move hulls and CV's around to make the basic shape of the head. Then it comes to a part where he wants to close the top of the cylinder (to represent the top of the head). He says he is creating a pole (?), which he says is bad, but that we will be removing it later. He does this by selecting the top Hull in the side view and then he does something to snap the points to 0, then goes to front view and does the same...i can't figure out how he is doing this. I just moved the points to 0 from the Channel box, but would love to know how he did it. I do know how how to snap a point to the grid, but i don't know how he is selecting the whole hull and snapping all the points to 0 at the same time. Any ideas?
