CenterLineReplacer

Replaces area geometries with their approximate center lines, medial axes, or straight skeletons. This transformer works best with long, narrow areas.

Output Ports

Parameters

Usage Notes

  • In the medial axis and straight skeleton modes, input areas must be non self-intersecting and simple (that is, the number of unique vertices must equal the number of edges)
  • Because Z coordinates are not considered in any mode's algorithm, all features processed by this function are forced to 2D.

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.
