curve
insertKnotCurve is undoable, queryable, and editable.
The insertKnotCurve command inserts knots into a curve given a list
of parameter values. The number of knots to add at each parameter value
and whether the knots are added or complemented can be specified.
The name of the curve is returned.
If construction history is on, the name of the resulting
dependency node is also returned.
An edit point will appear where you insert the knot. Also, the
number of spans and CVs in the curve will increase in the area where
the knot is inserted.
You can insert up to "degree" knots at a
curve parameter that isn't already an edit point. eg. for a
degree three curve, you can insert up to 3 knots.
Use this operation if you need more CVs in a local area of the curve.
Use this operation (or "hardenPoint") if you want to create a corner
in a curve.

Properties |
|
-addKnots(-add)
|
boolean
|
  
|
|
Whether to add knots or complement. Complement means knots will be added to reach the specified number of knots.
Default: true
|
|
-insertBetween(-ib)
|
boolean
|
|
|
If set to true, and there is more than one parameter value specified,
the knots will get inserted at equally spaced intervals between
the given parameter values, rather than at the parameter values
themselves.
Default: false
|
|
-numberOfKnots(-nk)
|
int
|
|
|
How many knots to insert. At any point on the curve, there can
be a maximum of "degree" knots.
Default: 1
|
|
-parameter(-p)
|
float
|
|
|
Parameter value(s) where knots are added
Default: 0.0
|
|
| Common flags |
-constructionHistory(-ch)
|
boolean
|
|
|
Turn the construction history on or off.
|
|
-curveOnSurface(-cos)
|
boolean
|
|
|
If possible, create 2D curve as a result.
|
|
-name(-n)
|
string
|
|
|
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.
|
|
-object(-o)
|
boolean
|
|
|
Create the result, or just the dependency node.
|
|
-replaceOriginal(-rpo)
|
boolean
|
|
|
Create "in place" (i.e., replace).
|
|
| Advanced flags |
-caching(-cch)
|
boolean
|
|
|
Modifies the node caching mode. See the node documentation for more information.
Note: For advanced users only.
|
|
-nodeState(-nds)
|
int
|
|
|
Modifies the node state. See the node documentation for more information.
Note: For advanced users only.

insertKnotCurve -ch on -p 0.3 -nk 2 curve1;

// Both commands will insert two knots into curve1 at parameter value 0.3.
// Because the -ch flag is used, a dependency node is created.
insertKnotCurve -ch on -add off -p 0.5 -nk 3 curve1;
// Inserts enough knots into curve1 at parameter value 0.5 to
// achieve a knot multiplicity of 3. Because the -ch flag is used,
// a dependency node is created.
insertKnotCurve -ch on -p 0.3 -p 0.5 -p 0.8 curve1;
// Inserts a default of one knot at each parameter value: 0.3, 0.5 and 0.8.
insertKnotCurve -ch on -p 0.3 -p 0.5 -p 0.8 -nk 2 curve1;
// Inserts two knots at each parameter value: 0.3, 0.5 and 0.8.
insertKnotCurve -ch on -p 0.1 -p 0.3 -p 0.5 -p 0.8 -nk 1-nk 2 curve1;
// Invalid command. The number of -nk flags doesn't match the number
// of -p flags.
