NurbsCurve Properties |

The NurbsCurve type exposes the following members.

Properties

Name | Description | |
---|---|---|

Degree |
Gets the maximum algebraic degree of any span
or a good estimate if curve spans are not algebraic.
(Inherited from Curve.) | |

Dimension |
Gets the dimension of the object.
(Inherited from Curve.)The dimension is typically three. For parameter space trimming curves the dimension is two. In rare cases the dimension can be one or greater than three. | |

Domain |
Gets or sets the domain of the curve.
(Inherited from Curve.) | |

HasBezierSpans |
Returns true if the NURBS curve has bezier spans (all distinct knots have multiplitity = degree)
| |

HasBrepForm |
Returns true if the Brep.TryConvertBrep function will be successful for this object
(Inherited from GeometryBase.) | |

HasUserData |
Gets true if this class has any custom information attached to it through UserData.
(Inherited from CommonObject.) | |

IsClosed |
Gets a value indicating whether or not this curve is a closed curve.
(Inherited from Curve.) | |

IsDeformable |
true if object can be accurately modified with "squishy" transformations like
projections, shears, and non-uniform scaling.
(Inherited from GeometryBase.) | |

IsDocumentControlled |
If true this object may not be modified. Any properties or functions that attempt
to modify this object when it is set to "IsReadOnly" will throw a NotSupportedException.
(Inherited from GeometryBase.) | |

IsPeriodic |
Gets a value indicating whether or not this curve is considered to be Periodic.
(Inherited from Curve.) | |

IsRational |
Gets a value indicating whether or not the curve is rational.
Rational curves have control-points with custom weights.
| |

IsValid | Tests an object to see if it is valid. (Inherited from CommonObject.) | |

Knots |
Gets access to the knots (or "knot vector") of this nurbs curve.
| |

ObjectType |
Useful for switch statements that need to differentiate between
basic object types like points, curves, surfaces, and so on.
(Inherited from GeometryBase.) | |

Order |
Gets the order of the curve. Order = Degree + 1.
| |

PointAtEnd |
Evaluates point at the end of the curve.
(Inherited from Curve.) | |

PointAtStart |
Evaluates point at the start of the curve.
(Inherited from Curve.) | |

Points |
Gets access to the control points of this nurbs curve.
| |

SpanCount |
Gets the number of non-empty smooth (c-infinity) spans in the curve.
(Inherited from Curve.) | |

TangentAtEnd | Evaluate unit tangent vector at the end of the curve. (Inherited from Curve.) | |

TangentAtStart | Evaluates the unit tangent vector at the start of the curve. (Inherited from Curve.) | |

UserData |
List of custom information that is attached to this class.
(Inherited from CommonObject.) | |

UserDictionary |
Dictionary of custom information attached to this class. The dictionary is actually user
data provided as an easy to use sharable set of information.
(Inherited from CommonObject.) | |

UserStringCount |
Gets the amount of user strings.
(Inherited from GeometryBase.) |
