Routing multi-layer boards with polygons

It is possible to create supply layers with polygons that contain more than one supply voltage, and individual wires as well.

Define the polygons before running Autorouter.
Give the appropriate signal names to the polygons.
Use the RATSNEST command to let Electronics calculate the polygon.
Select the preferred directions and base costs (cfBase) for the layer in Autorouter setup. A higher value of cfBase for the polygon layer causes the Autorouter to avoid these layers more strongly.
After routing, check that the polygon still connects all the signal points. It is possible that the polygon was divided as a signal was laid. RATSNEST recomputes polygons, and issues the message Ratsnest: Nothing to do!, if everything is in order.

Note:

Autorouter cannot set Micro vias. It is allowed to set Blind vias that are shorter than the maximum depth defined in the Layer Setup.
