Well, if the script is generic (rather than hard-coding which footprints you're looking for), it only ever has to be written once, and then used for many different footprints/layouts. The hardest part is searching paths for the updated footprints -- that part could be ripped from gsch2pcb (except that's written in C and this is a natural job for a higher-level language). > The cleanup after the script finishes may be more difficult than the cleanup > prior to doing a manual replace. If footprint changes are minor -- clearances, mask, silkscreen, etc., then cleanup should not be too bad. If you change pad widths or lengths, you might have problems.

I usually end up with boards that have components on different grids, and I often set up a module/cluster of components on one grid, then select and move it as a single mass, possibly onto another grid, and so the components then end up on a fractional grid of some sort. This is particularly likely when I'm using a metric grid on one module and imperial on another. The part I'm looking at right now ended up with its center on (1410.50,409.10), for one or both of those reasons (I can't really recall). For now, I have fixed my immediate problem with the power of emacs. Maybe I'll write that generic script, someday. -- Randall _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
