>From a practical standpoint, I think it makes sense to have a fast way to scan for layers of some high-level type, as well as further typing them by name. My original design had an enumerated type for each drawing layer, that was one of (for example) "copper, silk, soldermask, paste, outline, other" with flags for "normal, inverted" and an assignment to a physical layer (1..N). That way, when you're doing something compute-intensive like connectivity checks for "auto-enforce drc clearance" you aren't doing a bazillion string compares. Actions that are performed less often, like mapping a footprint to an element, can use a more open-ended string-attribute with more complex rules. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
