Message #09556
HPGL
Hello,
the plotted tracks from Pcbnew going from the center of pads or vias to
another center and cover up the center of pads or vias. With the
attached patch for only HPGL plots the tracks are terminated at the
border from pads or vias. The patch is not perfect, any work ist to do
on oval pads and segments in pads. But for now, it works for circle and
rectangle pads.
Regards, Andreas
