@samw FreeCAD does still scare me a little because I've settled into my cosy OnShape nook. I'm sure when the global internet explodes I'll be changing my tune tho lol

@samw That said, this does exist: https://github.com/easyw/kicadStepUpMod

design a new pcb Edge with FreeCAD Sketcher and PUSH it to an existing kicad_pcb Board

Not really a freecad user myself but might be useful depending on your application

@samw I'm willing to contribute to this bounty 👀
