Is Closed 3D

Summary

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

Usage

  • 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.

Syntax

arcpy.ddd.IsClosed3D(in_feature_class)
ParameterExplanationData Type
in_feature_class

The multipatch features to be tested.

Feature Layer

Derived Output

NameExplanationData Type
output_feature_class

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.
