Synopsis

hardenPointCurve( [curveName] , [constructionHistory=boolean], [curveOnSurface=boolean], [index=int], [multiplicity=int], [name=string], [object=boolean], [polygon=int], [range=boolean], [rebuild=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.

Flags

constructionHistory, curveOnSurface, index, multiplicity, name, object, polygon, range, rebuild, replaceOriginal
Long name (short name) [argument types] Properties
index(i) int queryeditmultiuse
index of the control vertex

In query mode, this flag needs a value.
multiplicity(m) int queryedit
the required multiplicity of the curve knot
Default: -1

In query mode, this flag needs a value.
name(n) string create
Name the resulting object
constructionHistory(ch) boolean create
Turn the construction history on or off (not available in all commands)
object(o) boolean create
Create the result, or just the dependency node (not available in all commands)
replaceOriginal(rpo) boolean create
Create "in place" (i.e., replace) (not available in all commands)
curveOnSurface(cos) boolean create
If possible, create 2D curve as a result (not available in all commands)
polygon(po) int create
The value of this argument controls the type of the object created by this operation (not available in all commands)
  • 0: nurbs surface
  • 1: polygon (use nurbsToPolygonsPref to set the parameters for the conversion)
  • 2: subdivision surface (use nurbsToSubdivPref to set the parameters for the conversion)
  • 3: Bezier surface
  • 4: subdivision surface solid (use nurbsToSubdivPref to set the parameters for the conversion)
range(rn) boolean create
Force a curve range on complete input curve (not available in all commands)
rebuild(rb) boolean create
Rebuild the input curve(s) before using them in the operation. Use nurbsCurveRebuildPref to set the parameters for the conversion. (not available in all commands)
Flag can appear in Create mode of command Flag can appear in Edit mode of command
Flag can appear in Query mode of command Flag can have multiple arguments, passed either as a tuple or a list.

Return value


[string[]] (object name and node name)

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

# Same result, as the in-between CVs are ignored:
