Spline Class

netDxf 3.0.0 Library

Represents a spline curve entity (NURBS Non-Uniform Rational B-Splines).

Definition

Namespace: netDxf.Entities
Assembly: netDxf (in netDxf.dll) Version: 3.0.0

C#

public class Spline : EntityObject

VB

Public Class Spline
	Inherits EntityObject

C++

public ref class Spline : public EntityObject

F#

type Spline = 
    class
        inherit EntityObject
    end

Inheritance
