Hi Wim, try the attached model - it has a couple of larger surfaces built in those areas and so it has a simplified topology which should be a lot more amenable to filleting.

Most of the time it is good to build the model in the way you were doing and rely on filleting to blend things together, but there are some kinds of cases where the filleter will get confused, that kind of thing with 2 sort of opposite oriented fillets coming together at a single juncture area is one of those.

Thanks Michael! that was a clear explanation (again)!

cheers

another solution is to cut the object in half do the vertical line fillets and rejoin
