Geometric Network properties example (stand-alone script)

The following stand-alone script displays properties for a geometric network.

import arcpy

# Create a Describe object from the geometric network.
#
desc = arcpy.Describe("C:/data/wellingham.gdb/water/water_Net")

# Print some geometric network properties
#
print "NetworkType:                    " + desc.networkType
print "OrphanJunctionFeatureClassName: " + \
    desc.orphanJunctionFeatureClassName
print "Feature Class Names:"
for fcname in desc.featureClassNames:
    print "  " + fcname
