Mick,
loaded your bbcd and dont see a problem with it however the code is not good. I tried changing to dia mode but still it was not good.
If I use my PP and use Dia mode (what I always use) then it is fine, well as long as Mach is in Dia mode as well.
So something wrong in the PP I think when it comes to rad mode. See what BobCAD say when you get them to do a PP for you.
