The NurbSpline type exposes the following members.
Methods

| ComputeDerivatives |
Returns the vectors describing the curve at the specified parameter.
(Inherited from Curve.) |
| ComputeNormalizedParameter | Computes the normalized curve parameter from the raw parameter. (Inherited from Curve.) |
| ComputeRawParameter | Computes the raw parameter from the normalized parameter. (Inherited from Curve.) |
 | Create(IList<(Of <<'(XYZ>)>>), IList<(Of <<'(Double>)>>)) |
Creates a new geometric NurbSpline object using the same calculations that Revit uses when sketching splines in the user interface.
|
| Create(IList<(Of <<'(XYZ>)>>), IList<(Of <<'(Double>)>>), IList<(Of <<'(Double>)>>), Int32, Boolean, Boolean) |
Creates a new geometric NURBSpline object.
|
| CreateOffset |
Creates a new curve that is an offset of the existing curve.
(Inherited from Curve.) |
| CreateReversed |
Creates a new curve with the opposite orientation of the existing curve.
(Inherited from Curve.) |
| CreateTransformed |
Crates a new instance of a curve as a transformation of this curve.
(Inherited from Curve.) |
| Dispose | Causes the object to release immediately any resources it may be utilizing. (Inherited from APIObject.) |
| Distance | Returns the shortest distance from the specified point to this curve. (Inherited from Curve.) |
| Equals | (Inherited from GeometryObject.) |
| Evaluate |
Evaluates and returns the point that matches a parameter along the curve.
(Inherited from Curve.) |
| GetEndParameter |
Returns the raw parameter value at the start or end of this curve.
(Inherited from Curve.) |
| GetEndPoint |
Returns the 3D point at the start or end of this curve.
(Inherited from Curve.) |
| GetEndPointReference | Returns a stable reference to the start point or the end point of the curve. (Inherited from Curve.) |
