Where is a description of how this backannotation works? Post layout renumbering is my biggest concern for backannotation. What is the mechanism for backannotation from PCB? If a third party tool provided a text based reference designator cross reference file, would it be possible to use the same mechanism as is used for the backannotation from PCB?
I was looking at the .sch files and it appeared that every reference designator was prefixed by refdes= so it seems like a very scriptable function if a simple cross reference file is available, even for a hardware guy. I was thinking of writing something to perform this task if necessary. Is there a gotcha I'm missing here?
