Object Model: NurbsCurve.Get2

NurbsCurve.Get2

Description

Returns a complete data description of the Nurbs Curve. The data is returned in a 1-dimensional array and is ordered the same as the NurbsCurve.Get method output arguments.

Note: This method must be used with scripting languages that don't support arguments passed by reference such as JScript and PerlScript. For more information on getting output arguments, see About Output Argument Arrays.

C# Syntax

Object NurbsCurve.Get2( siNurbsFormat in_eNurbsFormat );

Scripting Syntax

oArray = NurbsCurve.Get2( [NurbsFormat] );

Return Value

Array ordered as ControlPoints, Knots, Closed, Degree, Parameterization

Parameters

Parameter	Type	Description
NurbsFormat	siNurbsFormat	Specifies how the data is formatted. Default Value: siSINurbs
