Network Missing from Zone Fill

Layout
1

I want to declare the rear “green” zone in the attachment to cover network Net-D1-A. I thought that zone would appear in the network list when I "E"dit the green zone but it does not.
Am I misunderstanding something here?

Also I would think the zone, when filled, would confine itself to the board “edges” just as the GND (red) zone did.

Thanks for any advice

  • you can’t assign a zone to nets with auto-generated netnames (your Net-D1-A is autogenerated).
  • so first add a label to the net
  • than assign the zone to that labeled net

Also I would think the zone, when filled, would confine itself to the board “edges” just as the GND (red) zone did.

There is a difference:

  • GND-zone: remove islands == set to “always”
  • the bottom-side zone: remove islands == set to “never”

But the main problem: your board-outline is not closed. The inner shape is not continous (The startpoint of arcs and lines is not exactly the same as the endpoint of the previous segment). And with a bad board-outline the zone-filling doesn’t works correctly.

Thank you for your attention here. This all worked. I think the root cause was my upgrade from KiCAD 6–>7. It seems like ERC is checking more things. Curiously I went back to an older board and I hadn’t applied a label to the net–it still worked. Also I don’t recall the “islands–>never” issue ever being an issue before. I have played with the ERC parameters over the week and things seem about right now.
At any rate adding the label in this case worked fine. I was able to move ahead with ERC and find the open zones and fix them

regards
Fritz
