Is Closed 3D


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


  • This tool will add a new field called IsClosed that indicates whether a given feature is closed.

  • Consider using the Enclose Multipatch tool to construct closed features out of those that are not closed.

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'
IsClosed example 2 (stand-alone script)

The following sample demonstrates the use of 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

# Set environment settings
arcpy.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
