PCB based Rogowski coil

That up there is the ‘nudge’ :wink:

If you open a .kicad_pcb file in a text editor you can read what is in there, as it’s human readable.
All python does is create some string elements that KiCAD understands really - creating the positions for the many vias that you need and the pieces of copper tracks with their various positions (x,y).

This should give you an idea what’s involved..
