AddMassPoints Method

In This Topic

Adds points as nodes to the TIN. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public void AddMassPoints( 
   IEnumerable<MapPoint> points,
   int tagValue,
   double z,
   SpatialReference spatialReference
)

Public Sub AddMassPoints( _
   ByVal points As IEnumerable(Of MapPoint), _
   ByVal tagValue As Integer, _
   ByVal z As Double, _
   Optional ByVal spatialReference As SpatialReference _
)

Parameters

points: The points to add.
tagValue: The tag value for the new nodes. A value of 0 will result in no tag assignment.
z: The z-value for the new nodes. If you want to use the z-values from the points, call AddMassPointsZ(IEnumerable<MapPoint>,Int32,SpatialReference).
spatialReference: The spatial reference of the points. If it is the same as the TIN spatial reference, you can pass null.

Exceptions

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

Example

Add mass points

// Add points with no tag value and height = 17.
// The points have the same spatial reference as the tin editor, so there is no need to provide it. 
tinEditor.AddMassPoints(points, 0, 17);

// Add coordinates as nodes with tag value = 42. The height will come from the z-values of the coordinates.
tinEditor.AddMassPointsZ(coordinate3Ds, 42);

// Add z-aware points with tag value = 21. The height will come from the z-values of the points.
// The points are in a different spatial reference than the tin editor, so we provide the spatial 
// reference of the points. The points will be projected to the spatial reference of the tin editor.
tinEditor.AddMassPointsZ(pointsZ, 21, SpatialReferenceBuilder.CreateSpatialReference(54004));
