OrCAD PCB 16.6 - inconsistent anti-pads

embeddedTom

I've inherited a PCB design that's got some issues. The latest strangeness I've found is that it looks like only two via's have the correct anti-pad size (pic attached. Red circle shows correct anti-pad via's). All the via's are set to the correct size, but only two came out that way. The rest are oversized by a fixed amount (about 14 mils).

Still new to PCB 16.6, but I think I've searched all possible places that would change the anti-pad sizing, but cannot find the reason.

What did I miss?

Thanks.

Tom
