Hi,
I get some weird holes in all my layers with filled zones, next to a footprint of led’s.
Tried multiple times to update the zones (unfill and fill) and checked the footprints and layout for unwanted rule areas, but I could not find them. I am using KiCad 8.0.
Can anybody help with this issue?
First. Is there a good reason not to upgrade to 9? I’ve ‘promoted’ you to regular user in case it become necessary to upload the project file to see if this is repeatable.
Where did your footprints come from? Does your board or (your footprints) have any data on the ‘Margin’ layer and you have visibility for that layer turned off? Features on the ‘Margin’ layer are effectively a keep out on all layers to filled zones.
Thank you all for your responses!
Indeed, DaveL, the issue was the defined margin of 0.25mm between the pads of each LED. I deleted it in the corresponding footprint and now the shapes on the other layers are filled nicely without these discontinuities. However, I think the defined margin between two pads of 0.25mm should not lead to such weird holes on the other layers.
Kind Regards!
Don’t confuse the “display outline” and “display filled” buttons for updating the zones. Try hitting the “b” hotkey to refill the zones, or run a DRC.
It sounds for me like you are speaking about clearance but using word margin. I’m not exactly sure where from margin is named margin but it has the same function as Keep-out layer is Protel 3 I was using before KiCad. So any line at margin layer says “no copper at any layer can be here and with some clearance from this line”.
I suspect you may have downloaded the problematic footprint from Ultra Librarian, SnapEDA or the like? If so, these are often ‘translated’ to Kicad format rather than native and you have to check them and often ‘make them your own’ as they’ll often have data on layers you may not want/need and can even cause you problems- like you just experienced.
