I also tested this in 5.0.2. Same behavior.

I get a "corrupt file" message when trying to play that screen cast.

Is the bug that DRC doesn't report the error, or that routing lets you route a track into the keepout?

(I can reproduce the routing issue in Highlight Collisions mode, but I do still get DRC errors on OSX.)

@Jeff FWIW, I get the same "corrupt file" error, but after saving the file, I can play it with VLC flawlessly.

@Tom, this can be fixed by setting the keepout zone to net -1 in PNS_KICAD_IFACE::syncZone(), but I'm not sure if that's the "right" fix.

[Rene Poeschl (poeschlr)]

Sorry about the video being corrupted. (I only tested it in vlc and that one did not complain. But even youtube seems to complain when i try to upload it there.)

Truly unconnected pins are free to pass through the fill or ban cast zones. Make them non-intersecting with all the elements on the PCB.

[Rene Poeschl (poeschlr)]

Anton i have no idea how your comment applies to this report. We are not talking about pins here but about traces. Keepout for traces should not allow any traces. Not even "no-net" traces. (Such a keepout is typically used where no copper is allowed at all. If i want such a trace placed i can still select "allow DRC violations")

[Jeff Young (jeyjey)]

@Tom, any thoughts on comment #5?
