Do the twist... tadahhhhhh

 From:  Frenchy Pilou (PILOU)
In fact Twist or Bend are more Polygons functions of "box deformation"
That is a sort of perversion to use them in Nurbs :)
It's "post" modeling : spirit of nurbs is more think before for create curves generator

Sure when it's possible that give more flexibility to modeling ;)
