Boolean

hasNodeTagValues

(Read only)

Indicates whether the TIN dataset has node tag values.

Boolean

hasTriangleTagValues

(Read only)

Indicates whether the TIN dataset has triangle tag values.

Boolean

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)
