Adjust 3D Z (Data Management)—ArcGIS AllSource

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.
Use the Convert From Units and Convert To Units parameters to convert z-values from one common unit of measure to another.

Label	Explanation	Data Type
Input Features	The 3D features with the z-values that will be modified.	Feature Layer
Reverse Sign of Z Values (Optional)	Specifies whether features will be inverted along the z-axis. REVERSE—The sign of z-values will be inverted causing the feature to flip upside down. NO_REVERSE—The sign of z-values will not be inverted; it will be maintained. This is the default.	String
Adjust Z 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
Convert From Units (Optional)	Specifies the existing units of the z-values. This parameter is used in conjunction with the Convert To Units parameter. Millimeters—The units will be millimeters. Centimeters—The units will be centimeters. Meters—The units will be meters. Inches—The units will be inches. Feet—The units will be feet. Yards—The units will be yards. Fathoms—The units will be fathoms.	String
Convert To Units (Optional)	Specifies the units that existing z-values will be converted to. Millimeters—The units will be millimeters. Centimeters—The units will be centimeters. Meters—The units will be meters. Inches—The units will be inches. Feet—The units will be feet. Yards—The units will be yards. Fathoms—The units will be fathoms.	String

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")
