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.

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 )
# Result: [u'curve1'] #
