When I create a filled zone one pad stays unconnected while all others are. It happened after I’ve modified slightly the footprint and updated pcb. I cannot find a way for filled zone to be connected with this single pad. Any advice what is happening here?
Check the pad properties. Maybe that one pad is set to “do not connect to zones”
That was the case! Connect to Copper Zones option was set to None. I’ve fixed the option and now it creates connection to this pad.
