Hi Jeppe, Thanks for the patch. I'm not sure if we should define separate layers for cores/prepregs, though. How are they going to be stored in .kicad_pcb file? What if there is more than one layer of dielectric between each two adjacent layers? Maybe a new dialog for defining the complete stackup (including dielectric factors, losses, etc) would be a better idea?
