Hi Incoler, that's great. Putting on fillets in separate passes can make things more difficult basically because the new fillets now have to traverse the previous fillet geometry as well.

When it's done all at once then it's able to put in corner juncture patches where 2 fillets run into each other and that tends to help a lot.

But you can do the fillets in separate passes if you have some that you want to have a large radius, the large radius ones should go first.
