Feature

List

the joined polyline

Only LineString features are joined — anything else in the list is ignored, and if nothing qualifies, the node errors with "No lines to join."

How to

  1. Add the Join Lines node.

  2. Feed in a list of line features as "lines" — often from Read Static Layer, or several Line nodes collected with Encapsulate in List / Push.

  3. The output is a single polyline connecting them.
