--00000000000017bdc30592aac36e Content-Type: text/plain; charset="UTF-8" Please do report back! We haven't really received any feedback on the BBVias feature or its output. So, I'd really like to know if you have a success story. Of course, if it isn't such a story, I'd also really like to know so that I can fix it! :) Thanks, --Chad On Mon, Sep 16, 2019 at 3:10 AM Britton Kerin (britton DOT kerin AT gmail DOT com) [via geda-user AT delorie DOT com] <geda-user AT delorie DOT com> wrote: > On Sun, Sep 15, 2019 at 5:00 AM Chad Parker (parker DOT charles AT gmail DOT com) > [via geda-user AT delorie DOT com] <geda-user AT delorie DOT com> wrote: > > > > On Sat, Sep 14, 2019, 14:20 Bert Timmerman (bert DOT timmerman AT xs4all DOT nl) > [via geda-user AT delorie DOT com] <geda-user AT delorie DOT com> wrote: > >> > >> > >> The gerber files for copper, soldermask, silkscreen and outline should > >> not differ from a pcb with through hole vias. > > > > This isn't *quite* true.
