That's when we move over to block diagrams.

Sure, I could figure it out and somehow attempt to fix it but there are people in this community who could do that a lot better. Anyhow, I've mentioned further above in this thread what the problem is (renumbering messes up refdeses when only slot A has power visible). For me the solution right now is to just stick with my old CAD. Or maybe even resurrect ye olde OrCad. Somehow I often miss that old SDT, probably just like I'd wish I could have my first car back just one more time :-) -- Regards, Joerg http://www.analogconsultants.com/ _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
