How do you define a restrict area for inner layers of a 4 layer board?

Former Member

I can trestrict, and brestrict for the top and bottom, but I also need to

restrict an inner layer.  I'm trying to restrict the area for an antenna.  I

also have an inner ground layer that I need to restrict.

 

Thanks

    There are no "restrict" layers for the inner layers. You have to use

    polygons (eventually more than one) that have the correct outlines.

     

    You might also draw a wire of another signal name around the area that

    shall not be flooded. Of course this wire will be present in the board

    later. (But take care if something else, like a via, carries the

    polygon's signal in there...)

     

    I also have an inner ground layer that I need to restrict.

     

    "Supply layers" can not be restricted by definition. You have to change

    it to a normal routing layer and then use ground polygon(s).
