Hi Michael,

> Have you run into similar situations where boolean difference is not working with a large batch and it does work doing things in smaller groups?

Well, I did, but trying to reproduce it come out with positive results, funny that, it was when I was modelling the knurl on that thumb screw that I have a close up of in this thread, but I can't remember which version of MoI I did it in, was there any changes to the Booleans between the betas ? It was when doing the the crossing booleans that were intersecting the previous boolean that it failed, but then tried 3 or 4 at a time then it would work, it must of been just that situation, maybe it was a full moon that night ;) , so for now don't worry, I'll let you know when it happens again.

Cheers
