Feature To 3D By Attribute (3D Analyst)

License Level:BasicStandardAdvanced

Summary

Creates 3D features using height values derived from the attribute of the input features.

Usage

Syntax

FeatureTo3DByAttribute_3d (in_features, out_feature_class, height_field, {to_height_field})
ParameterExplanationData Type
in_features

The features that will be used to create 3D features.

Feature Layer
out_feature_class

The output feature class.

Feature Class
height_field

The field whose values will define the height of the resulting 3D features.

Field
to_height_field
(Optional)

An optional second height field used for lines. When using two height fields, each line will start at the first height and end at the second (sloped).

Code Sample

FeatureTo3DByAttribute 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.FeatureTo3DByAttribute_3d('Points2D.shp', 'Points3D.shp', 'Elevation')
FeatureTo3DByAttribute example 2 (stand-alone script)

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