Re: gEDA: changes for buried vias



thanks DJ for the feedback
I will certainly discuss iwth Dev. team any changes before I start.
I think 1-2 weeks are not really long time to wait...
Thanks

That would require a file format change. Please discuss the new
format with us before you start, as that's likely to affect your
changes. There's also been a little discussion about being able to
set pad/via annulus sizes and clearances separately for inner, top,
and bottom layers. It might be a natural thing to combine that with
blind/buried via support.

Plus, you might want to wait a week or so, we're just about to start
migrating the HID project into the official CVS repository; most of
the code will change and you wouldn't want to have to redo your work.

Might want to use HID exporters for these.

And HID is supposed to make it *easier* to follow :-)
