Moves the traits from one geometry onto another geometry. It can also move the attributes from a feature onto a geometry as traits, or the traits from a geometry onto a feature as attributes. The TraitMerger does not support attribute-attribute merges. For merging attributes between features, use the FeatureMerger.

Features that contain the desired attributes/traits are connected through the Supplier port, and the features that will receive the attributes/traits are connected through the Requestor port.

Requestor features/geometry are joined to Supplier features/geometry when the expressions specified in the Join On parameter ALL have the same value for both the requestor and supplier.

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.
