A feature I have heard previously requested is to be able to mark
certain layers as âno-DRCâ.  For instance, to allow special trace
elements such as antennas that the DRC thinks are incorrect shorts
between two nets. I also would like this so that the âoutlineâ layer or
extra layers with my own notes, calculations, fab notes, etc., are not
considered for DRC.
