extendCurve

Go to: Related nodes. Attributes.

Extend the start or end of the input curve. There are two methods used to specify where to extend to (extendMethod). The curve can be extended given a distance or given a point to extend to. In addition, the extension can be a linear, circular, or cubic segment (extendType). The extension can be joined to the original curve (join) and any unnecessary multiple knots at that join can be removed (removeMultKnots).
