What happens if you draw your no-net zone aa a simple rectangle
This is exactly what I would have wanted and how I understood previous instructions here. But I definitely cannot get it working in 6 dev. The dialog there looks a tad different so I guess work has been done here in the nightlies?
Here is a GND rectangle with prio 4 covering the entire board and then a no net zone with prio 0 surrounding the whole thing:
Still no covering fill.
It doesn’t seem to have anything to do with the fact that’s it a no-net fill though. Same goes if I try +12V which is actually in there too:
It just seems to me that the prio is used before the fill of the zone is calculated. So anything covered by the high prio GND fill will just be eaten up by that and later ditched to nothing because nothing connected.
