    ConstructMultipatchExtrudeAlongVector3D Method (GeometryEngine)
    In This Topic
    Creates a multipatch from the input polygon or polyline.
    public Multipatch ConstructMultipatchExtrudeAlongVector3D( 
       Multipart multipart,
       Coordinate3D coordinate
    Public Function ConstructMultipatchExtrudeAlongVector3D( _
       ByVal multipart As Multipart, _
       ByVal coordinate As Coordinate3D _
    ) As Multipatch


    The base geometry.
    The 3-dimensional coordinate.

    Return Value

    Returns the multipatch.
    Geometry is null or empty.
    The geometry is not Z-Aware.
    Creates a multipatch from a base geometry by extruding the base geometry along an axis defined by the input 3-dimensional coordinate. The base Z-values of the geometry are preserved and the top Z-values are offset from the base by the Z-value of the input coordinate. The top geometry is also shifted by an offset defined by the X-value and Y-value of the input coordinate. The resulting extrusion is parallel to the xy-plane if and only if the base geometry is parallel to the xy-plane.
    Construct Multipatch via Extrusion of Polygon or Polyline
    // build a polygon
    string json = "{\"hasZ\":true,\"rings\":[[[0,0,0],[0,1,0],[1,1,0],[1,0,0],[0,0,0]]],\"spatialReference\":{\"wkid\":4326}}";
    Polygon polygon = PolygonBuilderEx.FromJson(json);
    // extrude the polygon by an offset to create a multipatch
    Multipatch multipatch = GeometryEngine.Instance.ConstructMultipatchExtrude(polygon, 2);
    // a different polygon
    json = "{\"hasZ\":true,\"rings\":[[[0,0,1],[0,1,2],[1,1,3],[1,0,4],[0,0,1]]],\"spatialReference\":{\"wkid\":4326}}";
    polygon = PolygonBuilderEx.FromJson(json);
    // extrude between z values to create a multipatch
    multipatch = GeometryEngine.Instance.ConstructMultipatchExtrudeFromToZ(polygon, -10, 20);
    // extrude along the axis defined by the coordinate to create a multipatch
    Coordinate3D coord = new Coordinate3D(10, 18, -10);
    multipatch = GeometryEngine.Instance.ConstructMultipatchExtrudeAlongVector3D(polygon, coord);
    // build a polyline
    json = "{\"hasZ\":true,\"paths\":[[[400,800,1000],[800,1400,1500],[1200,800,2000],[1800,1800,2500],[2200,800,3000]]],\"spatialReference\":{\"wkid\":3857}}";
    Polyline polyline = PolylineBuilderEx.FromJson(json);
    // extrude to a specific z value to create a multipatch
    multipatch = GeometryEngine.Instance.ConstructMultipatchExtrudeToZ(polyline, 500);
    Coordinate3D fromCoord = new Coordinate3D(50, 50, -500);
    Coordinate3D toCoord = new Coordinate3D(200, 50, 1000);
    // extrude between two coordinates to create a multipatch
    multipatch = GeometryEngine.Instance.ConstructMultipatchExtrudeAlongLine(polyline, fromCoord, toCoord);
