Hi Sean, here's a repaired version of the smaller object. On this one the trimming boundaries were ok, the problem was that the underlying surface for that face was shifted some distance away from the trim boundaries. There's a bug in a geometry operation somewhere I think in filleting that does this rarely, I haven't been able to get a step-by-step example of how it happens which I'd need in order to get it fixed.

I'll see about the other piece next.
