Problem: I had to make a pointy curvy shape during NURMS, but in my case it would become dull during NURMS.
SOLUTION: So, pictures show the removed the edges so that there are only 2 edges left connecting to the the vertice that is the tip of the pointy-ness therefore leading to a pointyness in a NURMS smoothing. How is this practically useful I do not know for I am a noob, but I achieved my purpose.
Basically, as long as the the vertice is connected only to two edges, it can become pointy.
