OrCAD Layout - Round shaped PCB ?

Olilaf
Hi there, I'm in the process of designing a round shaped PCB in Layout. I've been searching google for the past days and it seems that no one ever needed to do such thing. I'm using OrCAD 16.0 suite. I've included a pdf so you guys might see what I'm talking about. The circuit must fit on the outer part. The center is actually empty, because I'm building this PCB around a shaft. files.getdropbox.com/.../shaft2.pdf Thanks Oliver

    When we did it, it was as simple as drawing it on the Board Geometry / Outline layer.  There was one shape for the outside edge of the PCB and another for the inside edge.  You would draw two concentric circle shapes with the proper diameter.  Aside from that, you should add Package and Route Keepouts to the center area especially if you use any Autorouting features.  That was good enough for our contract manufacturer to run with.
