SearchNodes Method (TinLayer)
In This Topic
Retrieves the nodes in the TIN that satisfy the criteria set in the . If no filter is set, all nodes will be retrieved. This method must be called on the MCT. Use QueuedTask.Run.
Syntax
Parameters
- filter
- Filter by parameters. See ArcGIS.Core.Data.Analyst3D.TinNodeFilter. If null, then all nodes are retrieved.
