Hmmm. The overall context is that it works. Re-reading my most recent
comments in isolation, it gets a little confusing. I blame the turkey, wine
(both exceedingly effective soporifics), and the resulting virtual jet-lag.
Yes, to all your comments. Eagle does indeed work well with pours, whether
for ground planes or any other signal you care to assign them. My last
remarks were in response to Evan, who deleted his ground plane and noted
that adding it back in works as expected. Which was in turn directed at my
earlier remarks regarding Eagle's obtuseness with pours on completely
complete boards. To which, we arrive back at the most immediate remarks that
deleting the ground plane leaves the board incomplete, and...
Or something like that.
