Hi crydee, yes filleting does tend to be a rather finicky area. There have been quite a bunch of improvements in version 2 though, and like Burr mentions the first one that you show there seems to work in v2.

The second one is a bit difficult overall, one thing that makes it harder for the filleter is that the edges are split up into several segments:



You may need to use surface/surface filleting more for some of these situations when the edge structure is not simple. Surface/surface filleting is a different mode for the filleter that is activated if you select 2 individual unjoined surfaces and then do Fillet.

Another thing that you may want to try is Blend rather than Fillet - for Blend you would would cut things back to leave some open space between piece rather than setting them up to touch exactly. Then you select edges and use Blend to fill in the open area with a smooth surface.

Blend can tend to be used somewhat more often than Fillet for the kind of stuff that you are doing there.


EDIT: Burr beat me to it with the same message! :)
