Enclose Multipatch (3D Analyst)

License Level:BasicStandardAdvanced

Summary

Creates closed multipatch features in the output feature class using the features of the input multipatch.

Usage

Syntax

EncloseMultipatch_3d (in_features, out_feature_class, {grid_size})
ParameterExplanationData Type
in_features

The multipatch features that will be used to construct closed multipatches.

Feature Layer
out_feature_class

The output closed multipatch features.

Feature Class
grid_size
(Optional)

The resolution used to construct the closed multipatch features. This value is defined using the linear units of the input feature's spatial reference.

Double

Code Sample

EncloseMultipatch example 1 (Python window)

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.EncloseMultiPatch_3d('unclosed_features.shp', 
                          'enclosed_features.shp', 0.5)
EncloseMultipatch example 2 (stand-alone script)

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

'''*********************************************************************
Name: Model Shadows For GeoVRML Models
Description: Creates a model of the shadows cast by GeoVRML models 
             imported to a multipatch feature class for a range of dates
             and times. A range of times from the start time and end 
             time can also be specified by setting the EnforceTimes 
             Boolean to True. This sample is designed to be used in a 
             script tool.
