If the input curve is open, then this node makes the curve periodic. If the input curve is periodic, then this node makes the curve open.

This node behaves as a toggle, ie. if a curve is closed twice, then the result is exactly the same as the original curve.

Use this node if want to close a curve such that it becomes curvature continuous along its entire length.

Long name (short name)TypeDefaultFlags
inputCurve (ic) nurbsCurveNULLoutputinputconnectable
The input curve
preserveShape (ps) enum1outputinputconnectablestorablekeyable
0 - without preserving the shape 1 - preserve shape 2 - blend
blendBias (bb) double0.5outputinputconnectablestorablekeyable
Skew the result toward the first or the second curve depending on the blend value being smaller or larger than 0.5.
blendKnotInsertion (bki) boolfalseoutputinputconnectablestorablekeyable
If set to true, insert a knot in one of the original curves (relative position given by the parameter attribute below) in order to produce a slightly different effect.
parameter (p) double0.1outputinputconnectablestorablekeyable
The parameter value for the positioning of the newly inserted knot.
outputCurve (oc) nurbsCurveNULLoutputconnectable
The output curve
