## DESCRIPTION

**This node specifies a NURBS curve that is used as a profile. The curve is defined in the same way as a standard SoNurbsCurve**, except that the control points are constructed from the current set of profile coordinates, using the **index** field.

## FIELDS

**SoMFFloat**	**knotVector**\
 The knot vector for the NURBS curve. It must be a list of non-decreasing floating point values.

## METHODS

	**SoNurbsProfile()**\
 Creates a NURBS profile curve node with default settings.

**static SoType**	**getClassTypeId()**\
 Returns type identifier for this class.

## ACTION BEHAVIOR

**SoGLRenderAction, SoCallbackAction, SoRayPickAction**\
 Adds a profile to the current traversal state.

## FILE FORMAT/DEFAULTS

```
NurbsProfile {
index	0
linkage	START_FIRST
knotVector	0
}
```
