ElevationExtractor
Extracts a feature’s first z coordinate value, storing it in an attribute.
Typical Uses
-
Extracting elevations from geometry to an attribute for further processing.
How does it work?
The ElevationExtractor receives any type of geometry and extracts the z coordinate value of the feature’s first coordinate into an attribute.
If the input feature is 2D, the Elevation output attribute will receive a value of zero (0).
Rasters, including elevation models, will also receive an elevation value of zero (0).

Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
Defining Values
There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.
Dialog Options - Tables
Transformers with table-style parameters have additional tools for populating and manipulating values.
