I am using Eagle Standard Edition, Version 5.11.0. I am placing a bluetooth-4 radio on a 4-layer board, and need to restrict the autorouter from placing any traces under the antenna. I use rectangles in the tRestrict, bRestrict, and vRestrict layers to keep the top and bottom layers clear. But how do I keep the autorouter from placing traces in the restricted area on the INTERNAL layers?
