UPDATE: The CADSTAR PCB Archive importer has now been merged into the master branch.This should trickle through into the nightly builds within the next few days.
Thanks to all the developers that have helped me along the way with my annoying questions and thanks especially to Seth Hillbrand (@Seth_h) for spending the time to do the final review on the code before merging!
I’ll now crack on with the CADSTAR Schematic Archive importer.
