Make TIN Layer (Data Management)


Creates a triangulated irregular network (TIN) layer from an input TIN dataset or layer file. The layer that is created by the tool is temporary and will not persist after the session ends unless the layer is saved to disk or the map document is saved.


  • The temporary layer produced by this tool can be saved as a layer file using the Save To Layer File tool.

  • This tool is useful for operations that require a TIN layer, such as the automation of map production through the arcpy.mapping module.
