ArcGIS.Core.Data.Analyst3D Namespace / TinTriangle Class / ToPolygon Method
Example

In This Topic
    ToPolygon Method
    In This Topic
    Gets this TIN triangle as a ArcGIS.Core.Geometry.Polygon. The spatial reference of the returned polygon is set to the spatial reference of the TIN. See TinDatasetDefinition.GetSpatialReference. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public Polygon ToPolygon()
    Public Function ToPolygon() As Polygon

    Return Value

    Exceptions
    ExceptionDescription
    This method or property must be called within the lambda passed to QueuedTask.Run
    Example
    TIN Triangles
    // nodes, edges of the triangle
    var triNnodes = triangle.Nodes;
    var triEdges = triangle.Edges;
    
    // triangle geometry
    var polygon = triangle.ToPolygon();
    // triangle length
    var triLength = triangle.Length;
    // triangle area 
    var triArea = triangle.Area;
    // is the triangle "inside"
    var isInsideTriangle = triangle.IsInsideDataArea;
    
    // triangle aspect and slope  (radians)
    var aspect = triangle.Aspect;
    var slope = triangle.Slope;
    
    // get centroid
    var centroid = triangle.GetCentroid();
    
    // get normal
    var normal = triangle.GetNormal();
    
    // get adjacent triangles
    var adjTriangles = triangle.GetAdjacentTriangles();
    
    // get area of triangle that falls between the z values
    double minZ = 1.0;
    double maxZ = 3.0;
    IReadOnlyList<Coordinate3D> coords = triangle.GetPointsBetweenZs(minZ, maxZ);
