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 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.
