I have a PCB project where there is an elevated island. I more or less finished designing the board but for some reason, when I want to run a DRC test, the GND copper pour on the island entirely disappears.
(alternatively, since I am happy with the island itself but I just want to move the island up a bit, If there is a way I can selectively redo copper pour, (performing GND copper pour on the main board’s copper layers only, that would be wonderful).
I do not know how to keep the island, as it is not connected to any pad/net, the job of the DRC is to remove it, I could not find any configuration to keep it, maybe throw a dummy pad on the bottom layer to keep the DRC happy.
Well if the island is anyway not attached to any net, maybe it can get its own net name that way you are able to redo the GND zone, without interfering with your Island.
As you can see in the FAQ article, it must be connected to a pad directly or indirectly. It’s not connected to a pad even indirectly through vias. It’s connected to a zone in B.Cu but that’s not connected to a GND pad, either.
