AddPolygons Method—ArcGIS Pro

AddPolygons Method

In This Topic

Adds polygons to the TIN. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public void AddPolygons( 
   IEnumerable<Polygon> polygons,
   TinSurfaceType tinSurfaceType,
   int tagValue,
   double z,
   SpatialReference spatialReference
)

Public Sub AddPolygons( _
   ByVal polygons As IEnumerable(Of Polygon), _
   ByVal tinSurfaceType As TinSurfaceType, _
   ByVal tagValue As Integer, _
   ByVal z As Double, _
   Optional ByVal spatialReference As SpatialReference _
)

Parameters

polygons: The polygons to add.
tinSurfaceType: The surface type which indicates how the polygons are to be incorporated into the tin. Polygons can be entered as polygon, line, or mass points surface types.
tagValue: The tag value to be assigned to the new elements in the TIN. If the surface feature type is set to mass points the tag is assigned to the resulting TIN nodes. If the surface type is lineal, then the tags are assigned to edges. If the surface type is polygonal, then the tags are assigned to triangles. A value of 0 will result in no tag assignment.
z: The z-values for the added geometries. If you want to use the z-values from the polygons, use AddPolygonsZ.
spatialReference: The spatial reference of the polygons. If it is the same as the TIN spatial reference, you can pass null. Otherwise, the polygons will be projected from the input spatial reference to the spatial reference of the tin.

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method must be called on the MCT. Use QueuedTask.Run.
System.ArgumentNullException	The polygons parameter is null.
ArcGIS.Core.Data.Exceptions.TinException	The editor is not in edit mode.
System.ArgumentException	The polygons are all null or empty.

Example

Add polygons

// Add polygons with tagValue = 42 and height = 12. 
// The polygons are in a different spatial reference than the tin editor, so we provide the spatial 
// reference of the polygons. The polygons will be projected to the spatial reference of the tin editor.
tinEditor.AddPolygons(polygons, TinSurfaceType.ZLessSoftLine, 42, 12, SpatialReferenceBuilder.CreateSpatialReference(54004));

// Add z-aware polygons with no tag value. The height comes from the z-values of the vertices. 
// The polygons are in the same spatial reference as the tin editor, so there is no need to provide it.
tinEditor.AddPolygonsZ(polygonsZ, TinSurfaceType.HardLine, 0);

Requirements

Target Platforms: Windows 11, Windows 10

ArcGIS Pro version: 3.5 or higher.
