Is Closed 3D (3D Analyst)

Summary

Evaluates multipatch features to determine whether each feature completely encloses a volume of space.

Usage

• A new field that specifies whether the multipatch is closed is added to the input multipatch feature.

• This tool is a 3D set operator that provides analytical functions on 3D features. See Working with 3D set operators for more information on what set operators are and how to use them.

Syntax

IsClosed3D_3d (in_feature_class)

Parameter	Explanation	Data Type
in_feature_class	The multipatch features to be tested.	Feature Layer

Code Sample

IsClosed example 1 (Python window)

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

import arcpy
from arcpy import env

env.workspace = 'C:/data'
arcpy.IsClosed3D_3d('sample_multipatch.shp')

IsClosed example 2 (stand-alone script)

The following sample demonstrates how to use this tool in a stand-alone Python script:

'''****************************************************************************
Name: IsClosed3D Example
Description: This script demonstrates how to use the 
             IsClosed3D tool on all multipatches in a target workspace.
****************************************************************************'''
# Import system modules
import arcpy
import exceptions, sys, traceback
from arcpy import env

try:
    # Obtain a license for the ArcGIS 3D Analyst extension
    arcpy.CheckOutExtension('3D')
    # Set environment settings
    env.workspace = 'C:/data'
    # Set Local Variables
    for fc in arcpy.ListFeatureClasses(): # list features in workspace
        # Determine which features are multipatches
        if arcpy.Describe(fc).shapeType == 'MultiPatch':
            # Execute Is Closed 3D
            arcpy.IsClosed3D_3d(fc)
    

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))
    # Return python error messages for script tool or Python Window
    arcpy.AddError(pymsg)
    arcpy.AddError(msgs)
