ArcGIS Pro 3.3 API Reference Guide
ArcGIS.Core.Data.Analyst3D Namespace / TinDataset Class / GetNearestEdge Method
Point location. This will be projected into the spatial reference of the TIN dataset.
Example

In This Topic
    GetNearestEdge Method
    In This Topic
    Gets the nearest edge to the specified point. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public TinEdge GetNearestEdge( 
       MapPoint point
    )
    Public Function GetNearestEdge( _
       ByVal point As MapPoint _
    ) As TinEdge

    Parameters

    point
    Point location. This will be projected into the spatial reference of the TIN dataset.

    Return Value

    Exceptions
    ExceptionDescription
    Point is null
    This method or property must be called within the lambda passed to QueuedTask.Run
    Remarks
    To ensure maximum robustness, callers should explicitly dispose of the returned TinEdge in either a using statement or a finally block.
    Example
    Access TIN Elements by MapPoint
    // "identify" the closest node, edge, triangle
    using (var nearestNode = tinDataset.GetNearestNode(mapPoint))
    {
    }
    
    using (var nearestEdge = tinDataset.GetNearestEdge(mapPoint))
    {
    }
    using (var triangle = tinDataset.GetTriangleByPoint(mapPoint))
    {
    
    }
    
    // get the set of natural neighbours 
    // (set of nodes that "mapPoint" would connect with to form triangles if it was added to the TIN)
    IReadOnlyList<ArcGIS.Core.Data.Analyst3D.TinNode> naturalNeighbors = tinDataset.GetNaturalNeighbors(mapPoint);
    
    // get the set of triangles whose circumscribed circle contains "mapPoint" 
    IReadOnlyList<ArcGIS.Core.Data.Analyst3D.TinTriangle> triangles = tinDataset.GetTriangleNeighborhood(mapPoint);
