I’ve just run into this problem as I had a few breakout boards that I am working on that are on the small side. When I added arcs to the corners of my board on the Edge.cuts layer to round off the corners. When I attempt to lay a track near the corner now, it prevents me from placing a track anywhere near the corner as if the entire circle of the arc was drawn on the board outline. I posted a picture that I hope roughly gets across the meaning of what I am trying to convey. Wondering if anyone else has noticed this and any way around it? I am running Kicad 5.1.2 latest stable build on a 64bit windows machine.
