You want to split a polygon into different nets? Does that work? Even if you invoke the special magic to not loose isolated parts of the polygon, will the connectivity check treat them as separate copper and assign them to different nets? I've drawn separate polys for each power/gnd net on my boards. Let's see, ok, it does work. I'd still be uncomfortable with such a layout. test.pcb Description: Binary data -- Stephan ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

gEDA-user: gnetlist "Possible attribute conflict..."
Recently, a new scheme function was added to gnetlist to check for all the attribute values a set of symbols with the same refdes might have. Unfortunately, this does not play nice with my most common use case for sets of symbols: Extra symbols for power pins of opamps and the like. In this case, I'd like to have the footprint and the value defined only once. If I do so, gsch2pcb does 1) warn about possible attribute conflict Possible attribute conflict for refdes: U1 name: footprint values: (#f SO8) 2) Assign the value "unknown" if the instance without the attribute is located before the others in the *.sch file. This is most probably not, what I want. Please make it so, that undefined or empty attributes are ignored in the list of attribute values. ---<)kaimartin(>--- -- Kai-Martin Knaak Email: k...@familieknaak.de Öffentlicher PGP-Schlüssel: http://pool.sks-keyservers.net:11371/pks/lookup?search=0x6C0B9F53 ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
