On PCBs I place some symbol like
CE or the WEEE etc.
They have empty REF***
When I run DRC, it detects them as duplicate.
Ok I normally ignore this BUT when I update the PCB with changes made in the schematics, if I don’t pay attention to uncheck the checkbox, these symbols are removed.
Is there another way to avoid this and to keep the symbols, I mean: preventing involuntary removing actions …
Put them in the schematic also and assign them a unique ref like any other component. Like what I do with mounting holes, mine have refs H1, H2, and so forth.
it worked super with the left side stuff … I never use dit because it was hidden and I never paid attention. Now I keep it constantly open.
Initially I have made a mistake: I selected the wrong component and it was not working of course :-p then I spotted the error I’ve made and it worked out splendidly
