I don’t find a way to simply copy a schematic from and old project to a new one. But it seems a workaround exists.
Tried to follow but I found problems:
- searching for schematic to append KiCad don’t see *.sch file. I have to manually copy the whole path
- “old” schematic is immediately copied in new schematic, sometime over the existing one. No way to copy and paste
- simbols coming from my libraries are substituted for that coming from "official libraries
