load attached file and re-route or drag in opengl mode , lines and vias must not trace inside keepout polygon or outside edge-cuts (pcb border ). Same as F.Cu polygon does .

Tank you for your superb job !!

@Tomasz,
I consider this a bug. Router in all modes (highlite, shove, walk around) should evade keepout area (where Keepout Options "No track" set), the same way like pins and tracks.

Issue is not so serious, because DRC drops "Track inside a keepout area" errors, still a bug IMO.
Opinions?

[PCB Wiz (1-pcb-wiz)]

I agree that router should be keep-out aware, when running.

Other shove routers certainly are keep-out aware, but maybe this was a speed compromise/trade off ?

However, Keepouts are usually not too many in a design, usually far fewer than pads.

[Vlad A. (elf128)]

Even if user carefully place all track around keep-out zone it's still a problem. Cause track locking doesn't work with interactive router as well.
And this one is the most annoying part. If you accidentally touch already placed track while routing something else, router often decide "to optimize" old track straightening it out through keep-out zone. This can happen when you're focused on other part of there board and then... bam... Surprise!!!

[Maciej Suminski (orsonmmz)]

Vlad, which version do you use, nightlies or stable? Locked tracks are respected by the PNS router, I have just tested the current master and it works ok.

If you encounter problems, please fill out a bug report, preferably with a board we could use to reproduce the issue. Thank you in advance.

I just found another issue with the keepout zone settings that is related to this bug. If the zone properties are set to allow tracks and vias in keepout zone, the router will not allow you to route in the keepout zone even though only the zone fill option is checked. The legacy canvas router behavior is correct.

[Wayne Stambaugh (stambaughw)]

I think this is a legitimate bug not a new feature.

[Nick Østergaard (nickoe)]

@Wayne, the issue about tracks in the keepout zones have been reported in https://bugs.launchpad.net/kicad/+bug/1748832

I have not marked it as a duplicate in case we consider this multiple bugs.
