Abstract: Thje bus extended object is intended for simplify drawing bundles of evenly spaced parallel traces. The two main use cases are differential pairs and parallel buses.

  The edit-object is a series of line objects (extobj::role=edit, on any layer). There can be multiple edit-objects. Parallel traces of fixed geometry at fixed pitch are rendered under each edit object on the target layer. Joints are properly handled as long as:

Note: junctions are not possible.

Extobj details:

When a cover line is converted into a bus, the following defaults are set up:

An example/test board is available.
