NurbsCurve Properties

Gets the maximum algebraic degree of any span or a good estimate if curve spans are not algebraic.

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.

Indicates if this object has been disposed or the document it originally belonged to has been disposed.

Gets or sets the domain of the curve.

Returns true if the NURBS curve has Bezier spans (all distinct knots have multiplicity = degree)

Returns true if the Brep.TryConvertBrep function will be successful for this object

Gets true if this class has any custom information attached to it through UserData.

Gets a value indicating whether or not this curve is a closed curve.

true if object can be accurately modified with "squishy" transformations like projections, shears, and non-uniform scaling.

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.

Gets a value indicating whether or not this curve is considered to be Periodic.

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

Returns true if the curve is a cubic, non-rational, uniform NURBS curve that is either periodic or has natural end conditions. Otherwise, false is returned.

Tests an object to see if it is valid.

Gets access to the knots (or "knot vector") of this NURBS curve.

Useful for switch statements that need to differentiate between basic object types like points, curves, surfaces, and so on.

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

Evaluates point at the end of the curve.

Evaluates point at the start of the curve.

Gets access to the control points of this NURBS curve.

Gets the number of non-empty smooth (c-infinity) spans in the curve.

Evaluate unit tangent vector at the end of the curve.

Evaluates the unit tangent vector at the start of the curve.

List of custom information that is attached to this class.

Dictionary of custom information attached to this class. The dictionary is actually user data provided as an easy to use shareable set of information.

Gets the amount of user strings.
