Hi all, new here. I am trying to copy an LED array PCB layout onto a new PCB tied to a new schematic with all the same LEDs already added. The designations for every LED and coupling cap are the same as on the new schematic. When I update PCB from schematic after copying the old layout to the new PCB it re-adds all the LEDs from the schematic, and when I delete those the connections don’t move to the copied in LEDS. Sorry if this is confusing. Any help is appreciated!
When you update PCB from schematic you have some options to check. One of them (top one, I think) determines if KiCad identifies symbols by their references (as you want) or by their automatic assigned identifiers (you don’t see them).
I have no KiCad at hand to check at the moment what is this option exact description.
During Update PCB from Schematic [F8] you have to enable the: Re-link footprints to schematic symbols based on their reference designators option. (And of course you do have to have matching reference designators between the schematic and the PCB too).
