Ejemplo de código

Ejemplo 1 de TinPolygonTag (ventana de Python)

The following sample demonstrates the use of this tool in the Python window:

import arcpy
from arcpy import env

arcpy.CheckOutExtension("3D")
env.workspace = "C:/data"
arcpy.TinPolygonTag_3d("tin", "tin_polytag.shp", "Tag_Value")
Ejemplo 2 de TinPolygonTag (secuencia de comandos independiente)

The following sample demonstrates the use of this tool in a stand-alone Python script:

'''****************************************************************************
Name: TinPolygonTag Example
Description: This script demonstrates use of the 
             TinPolygonTag tool to extract tag information 
             from each TIN in the target workspace.
****************************************************************************'''
# Import system modules
import arcpy
from arcpy import env
import exceptions, sys, traceback

try:
    arcpy.CheckOutExtension("3D")
    # Set environment settings
    env.workspace = "C:/data"
    # Set Local Variables
    TagField = "Code"
    # Create list of TINs
    TINList = arcpy.ListDatasets("*", "Tin")
    # Verify the presence of TINs in the list
    if TINList:
        # Iterate through the list of TINs
        for dataset in TINList:
            # Define the name of the output file
            Output = dataset + "_domain.shp"
            # Execute TinPolygonTag
            arcpy.TinPolygonTag_3d(dataset, Output, TagFieldField)
        print "Finished."
    else:
        print "No TIN files reside in {0}".format(env.workspace)
    arcpy.CheckInExtension("3D")
except arcpy.ExecuteError:
    print arcpy.GetMessages()
except:
    # Get the traceback object
    tb = sys.exc_info()[2]
    tbinfo = traceback.format_tb(tb)[0]
    # Concatenate error information into message string
    pymsg = 'PYTHON ERRORS:\nTraceback info:\n{0}\nError Info:\n{1}'\
          .format(tbinfo, str(sys.exc_info()[1]))
    msgs = 'ArcPy ERRORS:\n {0}\n'.format(arcpy.GetMessages(2))
