### Examples

#### 1. VBScript Example

    CreatePrim "Grid", "MeshSurface"
    SetSelFilter "Vertex"
    SelectGeometryComponents "grid.pnt[0,40]"
    logmessage "is point #0 a boundary ? " _
            & selection(0).SubComponent.ComponentCollection(0).IsBoundary
    logmessage "is point #40 a boundary ? " _
            & selection(0).SubComponent.ComponentCollection(1).IsBoundary
    ' Expected result:
    'INFO : is point #0 a boundary ? True
    'INFO : is point #40 a boundary ? False

#### 2. JScript Example

    NewScene( null, false );
    CreatePrim("Grid", "MeshSurface", null, null);
    SetSelFilter( "Vertex" );
    SelectGeometryComponents( "grid.pnt[0,40]" );
    logmessage( "is point #0 a boundary ? "
            + selection(0).SubComponent.ComponentCollection(0).IsBoundary );
    logmessage( "is point #40 a boundary ? "
            + selection(0).SubComponent.ComponentCollection(1).IsBoundary );
    // Expected result:
    //INFO : is point #0 a boundary ? true
    //INFO : is point #40 a boundary ? false
