Hi all!

Last announcement for this weekend from me. This feature is a dialog box 
that lets the user change subcircuit layer bindings. The 1.5 
minutes long example video is accessible at:

https://archive.org/details/subc_layer_binding

The example subcircuit contains 2 pins, 3 pads on the top layer, a via, a 
copper triangle on the bottom and some silk on the top.

The subcircuit has these objects in virtual layers. There is a layer 
recipe that describes how these virtual layers should be mapped to actual 
board layers. This recipe is edited when the layer bindings are changed.

First the bottom copper layer is redirected to be a silk, then a negative 
mask layer. Even the original silk graphics can be sent to the mask layer.

Regards,

Igor2
