The example below illustrates a set of topologically connected linework on the left and the output of the AreaBuilder transformer on the right. In the output, the topologically correct polygons are highlighted in blue where the linework formed closed shapes, while the lines that did not close are shown in red.

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.
