Is there and example where you would use Twist ?

Thanks

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 ;)

Twist, taper, and bend are important in any modeling paradigm.

Yes, that would be nice!

Also "flow along cure" would be useful!
