WebJul 28, 2014 · You can get all the information from a nurbs curve, including the knot vector, but there are no components for inserting knots, or inserting kinks, or inserting control-points. It can be done relatively easily using a scripted component. The question that remains is how do you want to define where you want these knots inserted? -- David Rutten
