Get2 (NurbsSurfaceMesh) *

Description

Returns a complete data description of a NurbsSurfaceMesh. The data is returned in a 1-dimensional array and is ordered the same as for the NurbsSurfaceMesh.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.

Scripting Syntax

    NurbsSurfaceMesh.Get2( [NurbsFormat] )

C# Syntax

    Object NurbsSurfaceMesh.Get2( siNurbsFormat in_eNurbsFormat );

Parameters

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

Return Value

Array of Variants ordered as Count, NbUControlPoints, NbVControlPoints, UKnots, NbUKnots, VKnots, NbVKnots, UClosed, VClosed, UDegree, VDegree, UParam, VParam.

Examples

JScript Example

    // This example shows how to retrieve the output arguments returned by NurbsCurveList.Get2
    var oRoot = Application.ActiveProject.ActiveScene.Root;
    var oGrid = oRoot.AddGeometry( "Grid", "NurbsSurface" );
    oGrid.subdivu = 1;
    oGrid.subdivv = 1;

    Duplicate( "grid", null, 2, 1, 1, 0, 0, 1, 0, 1 );
    AddToSelection( "grid,grid1", null, 1 );
    SIAssembleNurbsMesh( null, 0.150, 0, 0, 1 );
    SelectObj( "surfmsh" );

    // convert VB array to JScript array
