One question...

Theme: Signal polygons, ground planes (V19+)

How can I fade out a groundplane polygon? I only want to see signal tracks.
If the ground plane is "filled" which means processed, it is placed onto the copper layer (e.g. layer 2 or 16) and can not be faded out separately. If the ground plane is not filled, that means in the primitive state, it is placed on the "area" layer (e.g. layer 0 or 14) and can be faded out.

Please use item "Un-fill all polygons" in menu "Actions/ Ground planes". Now you can fade them out again.
