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.
