Re: gEDA-user: next PCB release - 1.99za vs 4.0



I apologize in advance if this has already been suggested somewhere in this thread, but one thing that I've thought about footprints while reading the thread is keepouts.

Allowing for putting keepouts in the footprints is a very important addition to whatever gets decided, but what about separating placement keepouts from trace keepouts? That is, a footprint (such as the battery mount mentioned previously) with a requirement not to place any parts between the tabs, but traces are fine? Unfortunately, though, it'd wind up like the silk layer issue - that is, they'd only be needed (or relevant, that is) on the top and bottom layers of the board.)

I suppose it's a question that could simply be covered with a design review or such, but I know I've made board errors in the past that would likely have been cleaned up with a simple "hey - you can't put a part there..." note from the DRC...

BTW, you've all got a really great tool going! I've used it for several designs now, and haven't had a (tool related) problem yet.

Thanks!

My thoughts were that each drawing layer (copper, silk, keepout,
whatever) could belong to a specific physical layer, "top", "bottom"
"all inner", or "all".  I suppose we'd need an "all outer" for
orthogonality.  The top/bottom magic are needed to map footprints on
import, but I suspect things like silk and mask will end up in
top/bottom instead of a specific layer like 0 or 3.

Drawing layers that belong to the same physical layer are in the same
layer group (duh).
