Hi Renato, sorry I didn't quite read your message carefully enough, I was just looking at your image. One other comment, you wrote:

Actually normally I would recommend doing the fillets at the end... I'm not sure why that did not work for you previously, again it is hard to know without being able to examine the particular case.

But when you end up with different fillets that are going to kind of cross over and touch each other, those should be applied all at the same time except in situations where you are going to have something like a much larger radius on some of them and then a final small radius on the cut-out piece.

Like for example here:


This one was ok to apply in different stages because the first one around the top edges was a much larger radius than the second one around the booleaned out edges.


But if you want them all to be of the same small radius then those are good to apply all at the same time.
