pymel.core.modeling.extendCurve

extendCurve(*args, **kwargs)

This command extends a curve or creates a new curve as an extension

Flags:

Long name (short name)		Argument Types	Properties
caching (cch)		bool
	Modifies the node caching mode. See the node documentation for more information.Note:For advanced users only.
constructionHistory (ch)		bool
	Turn the construction history on or off
curveOnSurface (cos)		bool
	If possible, create 2D curve as a result
distance (d)		float
	The distance to extend Used only for extendMethod is byDistance.Default:1
extendMethod (em)		int
	The method with which to extend: 0 - based on distance, 2 - to a 3D pointDefault:0
extensionType (et)		int
	The type of extension: 0 - linear, 1 - circular, 2 - extrapolateDefault:0
inputPoint (ip)		float, float, float
	The point to extend to (optional)
join (jn)		bool
	If true, join the extension to original curveDefault:true
name (n)		unicode
	Sets the name of the newly-created node. If it contains namespace path, the new node will be created under the specified namespace; if the namespace does not exist, it will be created.
noChanges (nc)		bool
nodeState (nds)		int
	Modifies the node state. See the node documentation for more information.Note:For advanced users only.Common flags
object (o)		bool
	Create the result, or just the dependency node
pointX (px)		float
	X of the point to extend toDefault:0
pointY (py)		float
	Y of the point to extend toDefault:0
pointZ (pz)		float
	Z of the point to extend toDefault:0
range (rn)		bool
	Force a curve range on complete input curveFlag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.
removeMultipleKnots (rmk)		bool
	If true remove multiple knots at join Used only if join is true.Default:falseAdvanced flags
replaceOriginal (rpo)		bool
	Create “in place” (i.e., replace)
start (s)		int
	Which end of the curve to extend. 0 - end, 1 - start, 2 - bothDefault:1

Derived from mel command maya.cmds.extendCurve

Example:

import pymel.core as pm

# to extend the start of a curve with a line of distance 3
pm.extendCurve( em=0, et=0, s=True, d=3.0 )

# to extend the end of a curve to a point
pm.extendCurve( em=2, s=False, ip=(1, 2, 3) )
