Another area that looks like a problematic structure is this area here:



Those 3 surfaces look like they're flat to one another but when I removed them and tried to create one single large plane (which is better for filleting), it would not build it there, which means that you've likely got another one of those very shallow crease type shapes in that area. That's going to make it difficult for any fillet to work that has to go through that zone.

Hi Michael,

thanks for looking into it. You helped me a lot with this one.
And yes, those were exactly the parts I wanted to fillet and which gave me headache.
I tried to get a little work around by rounding the curves before I`m using Sweep.
I´m not at a hundret percent know, but I´m quite happy with it because the model must not be perfect.

Here are some pictures of the original.







And here is my "final" result.



Cheers and all the best.

Hi Holger, it has turned out well!
