Greetings!
I’m working on a 4 layer board and I’ve specified In1.Cu to be completely filled as a copper GND plane. I’ve created VIAs near components with ground pins on the F.Cu layer and routed those pins to the GND VIAs.
When I look at only the In1.Cu it shows GND VIAs but they display as not connected to the ground plane. I have a connector that has ground pins thru holes that show a surround connected to the In1.Cu plane. I’ve tried manually adding connections from the copper plane to the GND VIAs but nothing shows a connection. Can I assume the ground plane will be connected to the GND VIAs when the board is made?
If kicad shows no connection in pcbnew then you will not get one in the gerber output either.
Make sure the vias are connected to the same net as the zone (vias like traces get the net from the pad they are connected to). Also make sure the via is on the layer where the zone is located (you could have placed a blind or buried via or a micro via which don’t connect to all layers). Make sure the clearance settings of your zone allow for a connection to be possible (especially if anything on another net is nearby).
And a screenshot of the affected area might help a lot to be honest.

OK, here is front and back of a region of the board:
Here is the In1.Cu layer same view:
If I highlight the GND Net the whole plane is highlighted so I guess
its OK:
I just figured the white surrounding the GND vias meant they were isolated
the same way the other Net vias are isolated from the GND plane.
Thanks for your help!
Well i fear it is not ok at all. You need to refill the plane as right now every THT pad and every via is connected to it no matter which net they are on. So what you have right now is a massive short circuit. (At least this is how the screenshot looks like. Could of course be an artefact of the jpeg compression)
This. Press B or choose Edit -> Fill All Zones. Does it change anything?
