I’m encountering an issue with copper clearance in KiCad. I’ve set the default clearance to 0.12 mm in the design rules. However, when I create a copper zone (GND) on the front layer, the clearance between the copper trace and the zone is only 0.06 mm.
I’m trying to understand why this is happening. Is there a setting or rule that might be overriding the default clearance? How can I ensure that the copper zone respects the 0.12 mm clearance from traces?
I created a custom rule to enforce a 0.07 mm trace-to-copper clearance for specific footprints, notably BGA fan-out. However, KiCad seems to apply this 0.07 mm clearance globally instead of just to those footprints—could my footprint-specific rule be overriding the default clearance? In DRC, traces under the default 0.12 mm clearance correctly trigger errors, but ground-plane violations don’t report any errors, even though the inspection tool measures only a 0.06 mm gap. Is this a bug, or do I need to update KiCad?
