Object Model: NurbsCurveList.AddCurve

NurbsCurveList.AddCurve

Description

Add a curve to the end of the curve list

C# Syntax

NurbsCurve NurbsCurveList.AddCurve( Object in_vsaControlPoints, Object in_vsadKnots, Boolean in_bClosed, Int32 in_lDegree, siKnotParameterization in_eParam, siNurbsFormat in_eNurbsFormat );

Scripting Syntax

oReturn = NurbsCurveList.AddCurve( ControlPoints, [Knots], [Closed], [Degree], [Parameterization], [NurbsFormat] );

Return Value

NurbsCurve

Parameters

Parameter	Type	Description
ControlPoints	1D or 2D Array	The control points used for creating the nurbs surface. The control points can be stored in a 1 dimensional array or in a 2 dimensional matrix (Ux4) of x,y,z,w values. The 1 dimensional array should contain a sequence of x,y,z,w values e.g. {Xo,Yo,Zo,...X(n-1),Y(n-1),Z(n-1),W(n-1)}.
Knots	Array of Doubles	An array of knot values.
Closed	Boolean	Specifies whether the nurbs surface is closed or not in U direction. Default Value: False
Degree	Long	Degree of the nurbs surface in U direction. Default Value: 3
Parameterization	siKnotParameterization	The parameterization factor of the nurbs surface in U direction. Default Value: siNonUniformParameterization
NurbsFormat	siNurbsFormat	Specifies how the data is formatted. Default Value: siSINurbs
