DATA—Edges representing the interpolation zone. This is the default.
SOFT—Edges representing gradual breaks in slope.
HARD—Edges representing distinct breaks in slope.
ENFORCED—Edges that were not introduced by the TIN's triangulation.
REGULAR—Edges that were created by the TIN's triangulation.
OUTSIDE—Edges that are excluded from the interpolation zone.
ALL—All edges, included those that were excluded from the interpolation zone.

Ejemplo 1 de TinEdge (ventana de Python)
El siguiente ejemplo muestra cómo usar esta herramienta en la ventana de Python:
arcpy.env.workspace = 'C:/data'
arcpy.ddd.TinEdge('tin', 'tin_edge.shp', edge_type='ENFORCED')
Ejemplo 2 de TinEdge (script independiente)
El siguiente ejemplo muestra cómo usar esta herramienta en un script independiente de Python:
"""****************************************************************************
Name: Create Terrain from TIN
Description: This script demonstrates how to create a terrain dataset using
features extracted from a TIN. It is particularly useful in
situations where the source data used in the TIN is not available,
and the amount of data stored in the TIN proves to be too large
for the TIN. The terrain's scalability will allow improved
display performance and faster analysis. The script is designed
to work as a script tool with 5 input arguments.
