TIN properties example

The following stand-alone script displays properties for a TIN. It also prints all the field names for the TIN.

import arcpy

# Create a Describe object
desc = arcpy.Describe("C:/data/antelope_island")

# Print TIN properties
print("%-21s %s" % ("HasEdgeTagValues:", desc.hasEdgeTagValues))
print("%-21s %s" % ("HasNodeTagValues:", desc.hasNodeTagValues))
print("%-21s %s" % ("HasTriangleTagValues:", desc.hasTriangleTagValues))
print("%-21s %s" % ("IsDelaunay:", desc.isDelaunay))
print("%-21s %s" % ("ZFactor:", desc.ZFactor))

# Print the field names in the TIN
print("\nFields in the TIN:")
for field in desc.fields:
    print("\t%s" % field.name)
