Hi Mala,

re:
> booled or trimmed (not sure which operation is here state of the art - I do not yet exactly the difference)

If you have a solid then booleans are good, the booleans cut pieces up and then decide which pieces to keep based on which solid volume they are contained inside of.

If you have open surfaces then that's usually when you should use Trim - Trim doesn't automatically decide which pieces to remove, you have to pick the pieces you want to get rid of.

On your model I'm not sure why Filleting doesn't work but if you break the object apart into individual surfaces you can use surface/surface filleting on it by selecting 2 surfaces at a time instead of edges.

I can help you do that, what radius do you want?

I would like to understand and learn it myself. And it is still in progress. So it does not make so much sense giving the diameter of filleting. One learning I have in the meantime is trim vs. bool. Here in the attached file I put the banana to the cylinder first with the Trim operation and then the Bool: Union joined together. Filleting with the separated surfaces did not work.

Hi Mala,

It's working for me over here, here is what it looks like:

A way to find the problem of fileting here is perhaps a problem in your banana.
If you use SelectNakededges on the banana, you will see a problem with double edges zone.
Perhaps, a problem in the banana's creation ?

Test this one with a reconstruction using loft and blend creation

Yup Phiro is right there is a naked edge on your base model here:
