synopsis.
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 |
parameter(p) |
float |
    |
|
Parameter value(s) where knots are added
Default: 0.0 |
|
numberOfKnots(nk) |
int |
|
|
How many knots to insert. At any point on the curve, there can
be a maximum of "degree" knots.
Default: 1 |
|
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 |
|
| 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. |
|
| Common flags |
name(n) |
string |
|
|
Name the resulting object |
|
constructionHistory(ch) |
boolean |
|
|
Turn the construction history on or off |
|
object(o) |
boolean |
|
|
Create the result, or just the dependency node |
|
replaceOriginal(rpo) |
boolean |
|
|
Create "in place" (i.e., replace) |
|
curveOnSurface(cos) |
boolean |
|
|
If possible, create 2D curve as a result |
