Hi Pilou, it is certainly possible to generate some fillets in this way, but you'll also have quite a bit of work to do to fill in corners and handle intersections between the different fillets.

But that's actually one of the nice things about a "hybrid" modeling system like MoI (where you can work on solids or also on individual surfaces and join them together later) - that you can get in there and construct a fillet manually in some cases where an automatic solver isn't able to handle it.

It is not exactly easy to do though.
