the fingers have historically been implemented as lines drawn with a round aperture. If the aperture size is too large (relative to the copper annulus) it sticks out into the hole or it doesn't fully connect. In the last couple of pcb snapshots there are multiple thermal options though. Just keep clicking (or is it shift-clicking) with the via tool to cycle through them. -Dan _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
