The NurbSpline type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | Clone | Returns a copy of this curve. (Inherited from Curve.) |
| 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(HermiteSpline) |
Creates a new geometric NurbSpline object from a HermiteSpline.
|
| Create(IList<(Of <<'(XYZ>)>>), IList<(Of <<'(Double>)>>)) | Obsolete.
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) | Obsolete.
Creates a new geometric NURBSpline object.
|
| CreateCurve(HermiteSpline) |
Creates a new geometric Curve object by converting the given HermiteSpline.
The created curve may be a NURBSpline or a simpler curve such as line or arc.
|
| CreateCurve(IList<(Of <<'(XYZ>)>>), IList<(Of <<'(Double>)>>)) |
Creates a new geometric Curve object from NURBS curve data containing just control points and weights.
The created curve may be a NURBSpline or a simpler curve such as line or arc.
|
| CreateCurve(Int32, IList<(Of <<'(Double>)>>), IList<(Of <<'(XYZ>)>>)) |
Creates a new geometric Curve object from NURBS curve data, which does not include weights.
The created curve may be a NURBSpline or a simpler curve such as line or arc.
|
| CreateCurve(Int32, IList<(Of <<'(Double>)>>), IList<(Of <<'(XYZ>)>>), IList<(Of <<'(Double>)>>)) |
