Ring PCB design

Howdy everyone.

I don’t dabble in PCB design often, if at all really, and my only familiarity is with a somewhat old version of Eagle, well before Autodesk picked them up.

At any rate, I’m trying to create a ring PCB. For the sake of argument, let’s call it 80mm OD, 60mm ID, but I can’t see any way to do this. Is this even possible within this tool? My hope is that it’s a simple definition of parameters without too much custom drawing, etc.

Did you try placing concentric arcs on the Mechanical Details layer?
