Layer 3D To Feature Class (3D Analyst)

License Level:BasicStandardAdvanced

Summary

Exports feature layers that have 3D properties defined to a multipatch feature class.

Usage

Syntax

Layer3DToFeatureClass_3d (in_feature_layer, out_feature_class, {group_field})
ParameterExplanationData Type
in_feature_layer

The input feature layer that has 3D properties defined.

Feature Layer
out_feature_class

The output multipatch feature class.

Feature Class
group_field
(Optional)

The field in the input feature class that identifies the features that will be combined into the same multipatch feature. The resulting attributes will be set to one of the input records.

Code Sample

Layer3DToFeatureClass 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.Layer3DToFeatureClass_3d("Points_3D.lyr", "Test.gdb/trees")
Layer3DToFeatureClass example 2 (stand-alone script)

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

'''****************************************************************************
Name: Layer3DToFeatureClass Example
Description: This script demonstrates how to use the 
             Layer3DToFeatureClass tool to create multipatches from all
             layers in a target workspace. The layer files are assumed to have
             been saved wtih 3D rendering from ArcScene.
