AddGeometry Method (TinEditor)

In This Topic

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

Syntax

C#
Visual Basic (Declaration)

public void AddGeometry( 
   Geometry geometry,
   TinSurfaceType tinSurfaceType,
   int tagValue,
   double z
)

Public Sub AddGeometry( _
   ByVal geometry As Geometry, _
   ByVal tinSurfaceType As TinSurfaceType, _
   ByVal tagValue As Integer, _
   ByVal z As Double _
)

Parameters

geometry: The geometry to add.
tinSurfaceType: The surface type which indicates how the polygons are to be incorporated into the tin. The surface types which are valid depend on the type of geometry being entered. Points can only be entered as mass points. Polylines can be entered as hard or soft breakline types or have their vertices entered as mass points. 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 geometry. If you want to use the z-values from the input geometry, use AddGeometryZ

Exceptions

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

Example

Add a geometry

// Add a point as a node with no tag value at height = 10. Points and multipoints can only be added as mass points.
tinEditor.AddGeometry(point, TinSurfaceType.MassPoint, 0, 10);

// Add a z-aware multipoint as a nodes with tag value = 12 at height equal to the z-values of the points. Points and multipoints can only be added as mass points.
tinEditor.AddGeometryZ(multipointZ, TinSurfaceType.MassPoint, 12);

// Add a polyline as hard lines with tag value = 42 and height = 17.
tinEditor.AddGeometry(polyline, TinSurfaceType.HardLine, 42, 17);

// Add a z-aware polygon as an erase polygon with no tag value and height equal to the z-values of the vertices.
tinEditor.AddGeometryZ(polygonZ, TinSurfaceType.HardErase, 0);
