How to Add Circular Board Cutout Area

csoon1

I'm using Orcad PCB Editor and despite completing some training I'm still having a hard time adjusting (maybe because I'm a long-time Altium user). Basically I am designing a probe card. From the basic probe card shape (let's just imagine a rectangular PCB), I wanted to add circular board cutouts (1. for the area where the probe tips are mounted, and 2. for the finger hole). I need help in systematically doing this.

All I have in my limited Orcad mind is simply adding a package with one gigantic circular padstack (unplated with large drill hole). I don't think this is the right way. If this was Altium I can simply create a simple circular outline then convert this into a board cutout. I know this is a simple question for some people but if you are willing to share your knowledge I would greatly appreciate it.

Thanks!

    In PCB Editor, Run command Tools » Convert » Create Board Cutout from Selected Primitives.

    Board cutouts are included in defining the board shape and represent apertures on the board. As such, they are layer independent. Applying this instruction will produce a board cutout. You can access the object properties via the Region dialog. To open this dialog, double-click the polygon pours cutout or right-click and select Properties from the pop-up menu. If you haven't already done so, place a closed boundary, using tracks and arcs, to define the outline of the board cutout that you wish to create. Ensure that all constituent track and arc primitives of this boundary are taken. After launching the command, the current board shape will be modified to include a void area defined by your selected limit. Only tracks and arcs may be employed to define the boundary and the bounds must be shut down.
