Creates offset parallel lines on either side of linear features.

Jump to Configuration

Typical Uses

  • Creating parallel lines to the left, right, or both sides of a linear feature

How does it work?

The OffsetCurveGenerator takes in line features and creates new lines on either side of the original. These new lines are placed at a specified Offset distance from the original, on the left and right-hand sides. There is a choice of how corners are created - round, mitered, or beveled.

The new offset lines are output as Right and Left, according to the orientation of the original 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.
