ComradeGibbon , vor einem Monat Englisch @foone Company I worked for in the 80's the draftsman laid out PCB''s at 4X scale using tape and stickers on acetate film. Also old etching process you hope it only etches the exposed copper. I swear that's why early PCB's had snaky traces instead of sharp corners.
