hardenPointCurve( curve , [caching=boolean], [constructionHistory=boolean],
[multiplicity=int],
[name=string], [nodeState=int], [object=boolean], [replaceOriginal=boolean])
Note: Strings representing object names and
arguments must be separated by commas. This is not depicted in the
synopsis.
hardenPointCurve is undoable, queryable, and editable.
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.limitations
The 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.
