Insert New Knots
3-D FFS > Process > Insert knots
Use this function to insert new knots into the de Boor mesh belonging to a freeform surface, without changing the associated B-splines. This can, for instance, be useful if you want to reduce the intervals for local modification of the freeform surface.
- First identify the surface.
- Next, determine the new knot by point specification.
- Select whether you want to insert the knot in n- or in m-direction.
The new knot is inserted in the de Boor mesh in the specified direction; the freeform surface itself does not change.
