I realized another way to do this. I have a program which collects ready made sub pcb files for a subpage. See: https://www.delorie.com/archives/browse.cgi?p=geda-user/2022/11/06/03:11:40 https://www.delorie.com/archives/browse.cgi?p=geda-user/2023/03/14/19:50:18 It takes ready made sub pcb files for a design and prepends the source syms refdes value to the contained elements and writes that out to the current directory, one file per source symbol. I could update that program to also change an elements value and solve your case in that way. That wouldn't help with bom files, but it makes it esier to make a pcb design with many sub pages/subpcbs. It expects the sub pcb files to be in the same dir and have the same base name as the sub sch file. Since I mostly do two layer pcbs, it also produces an upside down version of each subpcb. Run it on the top sch file, start a new pcb with your desired dimensions, for each collected sub pcb file "add layout" and place the buffer. Then when all sub pcbs are placed, run e.g. lepton-sch2pcb and complete the pcb. Regards, /Karl Hammar
