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).

Long name (short name)	Type	Default	Flags
inputCurve1 (ic1)	nurbsCurve	NULL
The curve to extend.
inputCurve2 (ic2)	nurbsCurve	NULL
The curve to extend to (optional). Currently not used.
inputSurface (is)	nurbsSurface	NULL
The surface to extend to (optional). Currently not used.
inputPoint (ip)	double3
The point to extend to (optional)
pointX (px) distance (double) 0cm X of the point to extend to
pointY (py) distance (double) 0cm Y of the point to extend to
pointZ (pz) distance (double) 0cm Z of the point to extend to
extensionType (et)	enum	0
The type of extension: 0 - linear, 1 - circular, 2 - extrapolate
extendMethod (em)	enum	0
The method with which to extend: 0 - based on distance, 2 - to a 3D point
start (s)	enum	1
Which end of the curve to extend. 0 - end, 1 - start, 2 - both
bothEnds (be)	bool	false
Obsolete. Use value 2 in start/s attribute instead of setting this.
join (jn)	bool	true
If true, join the extension to original curve
distance (d)	distance (double)	1cm
The distance to extend Used only for extendMethod is byDistance.
removeMultipleKnots (rmk)	bool	false
If true remove multiple knots at join Used only if join is true.
outputCurve (oc)	nurbsCurve	NULL
The extended curve
