Breaks input features into points, lines, or areas. Chopped features contain the same set of vertices as input features.

This is useful when outputting to a format that has limitations on the number of coordinates in each feature. It can also be used to crudely simplify complex objects.

All new features have the same attributes as the original feature had and are output via the Output port. The optional chopping indicator attribute can be used to distinguish output features which were chopped from output features which were not.


Usage Notes

  • Input arcs are stroked prior to chopping. If the chopping operation does not modify a stroked arc, the arc is unstroked and will be output untouched.

  • Area features are chopped in such a way as to preserve the original area of the feature. That is, the original area feature is cut into smaller areas, which if dissolved together, would match the original area. New vertices may be introduced into the area feature as it is chopped.

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.
