NurbsCurve Properties

The NurbsCurve type exposes the following members.

Public propertyDegree
Gets the maximum algebraic degree of any span or a good estimate if curve spans are not algebraic.
(Inherited from Curve.)
Public propertyDimension
Gets the dimension of the object.

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.

(Inherited from Curve.)
Public propertyDisposed
Indicates if this object has been disposed or the document it originally belonged to has been disposed.
(Inherited from CommonObject.)
Public propertyDomain
Gets or sets the domain of the curve.
(Inherited from Curve.)
Public propertyHasBezierSpans
Returns true if the NURBS curve has Bezier spans (all distinct knots have multiplicity = degree)
Public propertyHasBrepForm
Returns true if the Brep.TryConvertBrep function will be successful for this object
(Inherited from GeometryBase.)
Public propertyHasUserData
Gets true if this class has any custom information attached to it through UserData.
(Inherited from CommonObject.)
Public propertyIsClosed
Gets a value indicating whether or not this curve is a closed curve.
(Inherited from Curve.)
Public propertyIsDeformable
true if object can be accurately modified with "squishy" transformations like projections, shears, and non-uniform scaling.
(Inherited from GeometryBase.)
Public propertyIsDocumentControlled
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.)
Public propertyIsPeriodic
Gets a value indicating whether or not this curve is considered to be Periodic.
(Inherited from Curve.)
Public propertyIsRational
Gets a value indicating whether or not the curve is rational. Rational curves have control-points with custom weights.
Public propertyIsSubDFriendly
Returns true if the curve is a cubic, non-rational, uniform NURBS curve that is either periodic or has natural end conditions. Othewise, false is returned.
(Inherited from Curve.)
Public propertyIsValid
Tests an object to see if it is valid.
(Inherited from CommonObject.)
Public propertyCode exampleKnots
Gets access to the knots (or "knot vector") of this NURBS curve.
Public propertyObjectType
Useful for switch statements that need to differentiate between basic object types like points, curves, surfaces, and so on.
(Inherited from GeometryBase.)
Public propertyOrder
Gets the order of the curve. Order = Degree + 1.
Public propertyPointAtEnd
Evaluates point at the end of the curve.
(Inherited from Curve.)
Public propertyPointAtStart
Evaluates point at the start of the curve.
(Inherited from Curve.)
Public propertyPoints
Gets access to the control points of this NURBS curve.
Public propertySpanCount
Gets the number of non-empty smooth (c-infinity) spans in the curve.
(Inherited from Curve.)
Public propertyTangentAtEnd
Evaluate unit tangent vector at the end of the curve.
(Inherited from Curve.)
Public propertyTangentAtStart
Evaluates the unit tangent vector at the start of the curve.
(Inherited from Curve.)
Public propertyUserData
List of custom information that is attached to this class.
(Inherited from CommonObject.)
Public propertyUserDictionary
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.)
Public propertyUserStringCount
Gets the amount of user strings.
(Inherited from GeometryBase.)
