Synopsis

hardenPointCurve [-caching boolean] [-constructionHistory boolean] [-multiplicity int] [-name string] [-nodeState int] [-object boolean] [-replaceOriginal boolean] curve

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.

Return value

string[]Object name and node name

In query mode, return type is based on queried flag.

Flags

caching, constructionHistory, multiplicity, name, nodeState, object, replaceOriginal
Long name (short name) Argument types Properties
-multiplicity(-m) int createqueryedit
the required multiplicity of the curve knot
Default: -1
Advanced flags
-caching(-cch) boolean createqueryedit
Modifies the node caching mode. See the node documentation for more information.
Note: For advanced users only.
-nodeState(-nds) int createqueryedit
Modifies the node state. See the node documentation for more information.
Note: For advanced users only.
Common flags
-name(-n) string create
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.
-constructionHistory(-ch) boolean create
Turn the construction history on or off
-object(-o) boolean create
Create the result, or just the dependency node
-replaceOriginal(-rpo) boolean create
Create "in place" (i.e., replace)
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 be used more than once in a command.
