Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.
pointCurveConstraint is undoable, queryable, and editable.
The command enables direct manipulation of a NURBS curve. It does so
by apply a position constraint at the specified parameter location on
the NURBS curve.
If construction history for the cmd is enabled, a locator is created
to enable subsequent interactive manipulation of the curve. The
locator position may be key framed or transformed and the "curve1"
will try to match the position of the locator.
The argument is a curve location

Properties |
pointConstraintUVW(puv)
|
[float, float, float]
|
  
|
|
Point constraint parameter space location on input NURBS Object
|
|
pointWeight(pw)
|
float
|
|
|
Point constraint weight. Determines how strong an influence the constraint has on the input NURBS object.
Default: 1.0
|
|
| 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.
|
|
position(p)
|
[float, float, float]
|
|
|
The new desired position in space for the nurbs object
at the specified parameter space component. If not specified,
the position is taken to be the one evaluated at the parameter
space component on the nurbs object.
|
|
weight(w)
|
float
|
|
|
weight of the lsq constraint. The larger the weight,
the least squares constraint is strictly met.
|
|
| Common flags |
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.
|
|
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)
|
|
|
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.
