Yeah, sorry the terminology can be a problem.

The object that you originally wanted to fillet I would have called an "Edge" curve, emphasis on the edge. This is a curve that is a part of the trimming boundary of a surface, it is associated with the surface.

If I just say "Curve" by itself (not edge), then I'm talking about a curve that is not a part of a surface at all, like a line or a circle. Sometimes I might call this a "Standalone curve".

You can fillet two standalone curves with each other similar to the way that you can fillet the edge of a solid, it will put an arc segment between them. Once you have constructed that arc curve segment, you would be able to revolve it which would create the fillet surface that you wanted in this case (that should have been made by the fillet command if it was working properly on that edge).

Here's another quick example of curve filleting just try and clarify it - draw two lines that cross each other like an X. Then pick the two lines, and hit the fillet button. The two lines will be trimmed back and an arc of the specified radius (either typed in, or the distance between the 2 points you pick with the mouse) will be in between them, tangent to each line. This works on any 2 curves though, not just lines.

Does that make sense?

The way filleting works is if you pick 2 curves, filleting will generate the fillet arc curve between the curves.

If you pick a solid, all the edges of the solid will fillet.

If you pick edges of a solid, just those edges will fillet.

If you pick any faces of a solid (meaning any of the surfaces that make up the solid), all the edges that border that face will fillet. This can often times be a quicker way to fillet a bunch of edges rather than selecting them all edge by edge.

There's also one other variant - if you pick 2 individual surfaces (that are not joined to any other surface), you will get a surface/surface fillet which is a slightly different operation than the joined edge fillet. There may be some cases where the surface/surface fillet will succeed where an edge fillet would fail, but not in this particular case.

Cool!

It's not possible yet, but it is planned. It probably won't be too terribly long before getting this, maybe within a few weeks or so...

If anything I've said here still doesn't make sense, don't hesitate to ask for more clarification.
