Jump to Configuration

Typical Uses

  • Cleaning up features with small numbers of unnecessary attribute
  • Improving performance by removing unneeded attributes

How does it work?

Once connected to input features, the AttributeRemover provides pick lists (one for attributes and one for list attributes) for you to choose which specific attributes to remove. All other attributes are kept, and the modified features are output.

Examples

Usage Notes

  • Consider using the AttributeManager instead
  • Use the BulkAttributeRemover to remove all attributes that match a pattern.
  • Use the AttributeKeeper to keep selected individual attributes on a feature.
  • Removing attributes can improve Workbench performance, making translations run more efficiently and the Workbench interface respond more quickly.

Parameters

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.
