Hello, I have seen some vintage PCBs (60's-80's) that have completely round corners in their copper tracks layout.
How did they do it? did they use some kind of CAD software back then or just paint it by hand?
Any such CAD software available forgotten somewhere?

Early stuff was done by tape on a transparency, I think. You could buy curved tape sections with different radii I think.

Are you asking whether current software will do that? Eagle 5.xx does.

The IC CAD software I use, will draw donuts which
you can then chop to make whatever angle of bend
you like. The path function is all ortho though. And
everything conic gets converted to 20-side polygons
in the end.

I just found that the latest EAGLE can do this.

A lot of PCB software can do arcs because you want them for RF layout.
