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>)>>)) |
Creates a new geometric Curve object from NURBS curve data, which includes weights.
The created curve may be a NURBSpline or a simpler curve such as line or arc.
| |

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.) | |

GetHashCode |
Gets the integer value of the geometry object as hash code
(Inherited from GeometryObject.) | |

GetType | Gets the Type of the current instance. (Inherited from Object.) | |

Intersect(Curve) | Calculates the intersection of this curve with the specified curve. (Inherited from Curve.) | |

Intersect(Curve, IntersectionResultArray%) | Calculates the intersection of this curve with the specified curve and returns the intersection results. (Inherited from Curve.) | |

IsInside(Double) | Indicates whether the specified parameter value is within this curve's bounds. (Inherited from Curve.) | |

IsInside(Double, Int32%) | Indicates whether the specified parameter value is within this curve's bounds and outputs the end index. (Inherited from Curve.) | |

MakeBound | Changes the bounds of this curve to the specified values. (Inherited from Curve.) | |

MakeUnbound | Makes this curve unbound. (Inherited from Curve.) | |

Project | Projects the specified point on this curve. (Inherited from Curve.) | |

SetControlPointsAndWeights | Set the control points, weights simultaneously. | |

SetGraphicsStyleId | Sets the graphics style id for this curve. (Inherited from Curve.) | |

Tessellate | Valid only if the curve is bound. Returns a polyline approximation to the curve.
(Inherited from Curve.) | |

ToString | Returns a string that represents the current object. (Inherited from Object.) |
