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.

Holger
