Creates two-point extensions to linear features that extend the feature by a user-specified length.

This transformer can also output the original feature with the first and last segments stretched by a user-specified amount. Each of the created features gets a copy of all attributes of the original feature, including the feature type.

Arcs that are input are converted to lines before processing, and extension lines are placed tangent to the arc.

Usage Notes

  • This transformer can be used in combination with the Snapper to perform a simple form of data cleaning.

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.
