--000000000000dedbb405b0ecd610 Content-Type: text/plain; charset="UTF-8" If you set the clearance of a pad to zero inside a polygon, you should get a "Pad with insufficient clearance inside polygon" error, not a "copper areas too close error". If you're getting the latter, that's a bug and we should fix it. Are you building from source? Have you run the tests? The DRC now has a pretty comprehensive set of test cases, and I would expect this to be flagged. A quick test with 4.2.0 on Win10 flags this correctly. It should, however, throw an error. It is technically breaking a design rule, even if you're doing it intentionally. The consequences of making such a connection unintentionally is quite high, and so it's safer, IMO, to throw the error and have you verify that the connection is intentional. Yes... we need more flexibility here. I'm aware. Also, SM pad thermals are high on my priority list, the availability of which I would expect to make this a non-issue. --Chad On Sun, Oct 4, 2020 at 12:55 AM Britton Kerin (britton DOT kerin AT gmail DOT com) [via geda-user AT delorie DOT com] <geda-user AT delorie DOT com> wrote: > Unfortunately the DRC will still > report a violation for the pad, but this warning can be ignored. > Incidentally, is it really correct to report "copper areas too close" > when the clearance assigned to the pad in question is 0?
