Hi,
Lachlan sent me a complex board in Eagle that has several copper zones,
each with different clearances, which filled incorrectly or didn't fill
at all. There were some trivial issues (e.g. inverted filling priority),
but there is one that needs discussion:
In pcbnew, each zone must have manually assignned clearance (in the
property window). In Eagle or Altium, if there's no clearance specified,
the program takes the clearance set in the Design Rules for the net the
zone belongs to.
I propose to add a similar feature to Kicad, that is:
- add a checkbox "use custom clearance" in the zone properties window
- if not checked, take the netclass clearance.
This unfortunately requires a small file format change. Would you agree
with that?
Also, many thanks to Lachlan for spotting this problem!
Cheers,
Tom
