Adjust 3D Z (Data Management)—ArcGIS Pro

Summary

Modifies Z-values of 3D features.

This tool modifies the input data. See Tools that do not create output datasets 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.

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")
