Extend Curve

Extend a curve by a given distance from one or both of its ends, returning the extended curve as a Polycurve.

Name	Type	Description
Curve	Curve	Curve to extend.
Distance	Scalar	Distance by which to extend the curve.
Extend from	Extend From Enum	End or ends of the curve to extend from.
Extension type	Extension Type Enum	Method of extension. Linear (G1) appends a straight line along the end tangent. Curvature (G2) extends along a circular arc matching the end tangent and curvature; always well-behaved. Natural (G-infinity) analytically continues the curve’s own equation for an infinitely smooth junction, capping the analytic part before it can fold back on itself and continuing with an arc.
