AttributeCreator

Adds one or more attributes to the feature and optionally assigns a value derived from constants, attribute values, and expressions. Values can reference adjacent features.

Jump to Configuration

Typical Uses

  • Add a new attribute to a feature and assign it a value
  • Add a new empty attribute to a feature for use elsewhere in the workspace

How does it work?

Blank rows are provided where you can enter new attribute names and (optionally) set values for them. One or more new attributes may be added, and all features that pass through the transformer are modified according to these selections.

New attributes are added at the top. Duplicate names are not identified, and are not added more than once.

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.
