I suspect that in the main GUI you'd get a simplified set of options, like "add layers" or "remove layers" to switch from, say, 2-layer PCBs to 4-layer PCBs, etc. Outer special layers like silk and mask just exist, but you can enable/disable them.
So most users just see one "copper" drawing layer per physical copper layer, plus the usual top/bottom silk/mask/paste, plus an outline. But if you're in "footprint mode" you get top/inner/outer instead, plus the usual t/b s/m/p. Footprints are a special case of sub-assembly that never use specific layers, always layer classes, so they can map to your boards. Power users can change the association for a layer, so for example, one could create a footprint with copper on ALL layers, for a heatsink or physical strength. Or a both-sides silkscreen layer. Or two copper drawing layers per physical copper layer. I've used this before, to keep ground/power/signal colored differently. Gold finger plating might take advantage of this too, or multiple conductor types (metal plate over copper, conductive ink). Or two silkscreen layers for different ink colors. I don't know what people are going to be using it for, so it made sense to just let them do whatever they please, if they know what they're doing. Like I've said before, I want to make things easy for most users, and possible for the rest. As for the color scheme, I suspect it will be plaid. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
