Adjust 3D Z (Data Management)—ArcGIS Pro

Summary

Modifies Z-values of 3D features.

This tool modifies the input data. See Tools that modify or update the input data for more information and strategies to avoid undesired data changes.

Consider inverting Z values of bathymetry and other subsurface measurements that use positive values to denote depth.
The Convert From Units and Convert To Units parameters allow you to convert Z-values from one common unit of measure to another.

arcpy.management.Adjust3DZ(in_features, {reverse_sign}, {adjust_value}, {from_units}, {to_units})

Parameter	Explanation	Data Type
in_features	The 3D features whose Z values will be modified.	Feature Layer
reverse_sign (Optional)	Specifies whether features will be inverted along the Z-axis. REVERSE —Inverts the sign of Z-values causing the feature to flip upside down. NO_REVERSE —Maintains the sign of Z-values. This is the default.	String
adjust_value (Optional)	A numeric value or field from the input features that will be used to adjust the Z of each vertex in the input features. A positive value will shift the feature higher, while a negative number will shift it lower along the Z-axis.	Double; Field
from_units (Optional)	The existing units of the Z-values. This parameter is used in conjunction with the Convert To Units parameter. MILLIMETERS —Millimeters CENTIMETERS —Centimeters METERS —Meters INCHES —Inches FEET —Feet YARDS —Yards FATHOMS —Fathoms	String
to_units (Optional)	The units that existing Z-values will be converted to. MILLIMETERS —Millimeters CENTIMETERS —Centimeters METERS —Meters INCHES —Inches FEET —Feet YARDS —Yards FATHOMS —Fathoms	String

Name	Explanation	Data Type
out_feature_class	The updated input features.	Feature Layer

Adjust3DZ example 1 (Python window)

The following sample demonstrates the use of this tool in the Python window.

arcpy.env.workspace = "C:/data"
arcpy.Adjust3DZ_management("subsurface_pts.shp", "REVERSE", 0, "METERS", "FEET")

Adjust3DZ example 2 (stand-alone script)

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

arcpy.env.workspace = "C:/data"
arcpy.Adjust3DZ_management("subsurface_pts.shp", "REVERSE", 0, "METERS", "FEET")
