pymel.core.modeling.hardenPointCurve¶

hardenPointCurve(*args, **kwargs)¶

The hardenPointCurve command changes the knots of a curve given a list of control point indices so that the knot corresponding to that control point gets the specified multiplicity. Multiplicity of -1 is the universal value used for multiplicity equal to the degree of the curve.limitationsThe CV whose multiplicity is being raised needs to have its neighbouring CVs of multiplicity 1. How many neighbours depends on the degree of the curve and the difference in CV multiplicities before and after this operation. For example, if you’re changing a CV of multiplicity 1 into a CV of multiplicity 3, you will need the 4 neighbouring CVs (2 on each side) to be of multiplicity 1. The CVs that do not satisfy that requirement will be ignored.

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.
frozen / fzn		bool
multiplicity / m		int
	the required multiplicity of the curve knot Default:-1 Common flags
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.
nodeState / nds		int
	Modifies the node state. See the node documentation for more information. Note:For advanced users only. Flag can have multiple arguments, passed either as a tuple or a list.
object / o		bool
	Create the result, or just the dependency node.
replaceOriginal / rpo		bool
	Create in place(i.e., replace). Advanced flags

Derived from mel command maya.cmds.hardenPointCurve

Example:

import pymel.core as pm

# Make the example curve.
pm.curve( d=3, p=((-7.253894, 0, 10.835724), (-7.423939, 0, 6.977646), (-7.400778, 0, 2.798971), (-7.458196, 0, -1.524959), (-2.411453, 0, -1.07677), (1.44791, 0, -0.8977448), (5.526346, 0, -0.8610371), (5.740407, 0, 3.780402), (6.293634, 0, 7.571941), (5.957847, 0, 10.72273), (2.753946, 0, 10.894312), (-0.6375988, 0, 11.062571), (-5.889847, 0, 10.940658)), k=(0, 0, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10) )
# Result: nt.Transform(u'curve1') #

# Raise the ones that you want to have "sharp" corners
pm.hardenPointCurve( 'curve1.cv[3]', 'curve1.cv[6]', 'curve1.cv[9]', ch=True, rpo=True, m=-1 )
# Result: [u'curve1'] #

# Same result, as the in-between CVs are ignored:
pm.undo()
pm.hardenPointCurve( 'curve1.cv[0:12]', ch=1, rpo=1, m=-1 )
