Replaces the geometry of the feature with a point that is either in the center of the feature's bounding box, at the center of mass of the feature, or somewhere guaranteed to be inside the feature's area.

If the Mode is Center Point of Bounding Box or Center of Gravity Point, depending on the feature's shape, the resulting point may be far outside of the original feature.


The following illustration shows the result when the Mode is Center of Gravity Point. The transformer calculates the exact distribution of portions of a shape; therefore, some points can actually appear outside a feature.

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.
