Hi Peter, you can do a fillet there, but it is not quite the same shape as doing a large single flowing piece.

Like you mention a "match" tool will be useful as another way to get smooth shapes, no doubt about that.

But there are several issues that tend to make it more difficult to get a totally flowing result. Even when things are technically smooth to one another, it can be easy for there to be a kind of "bulging" between surfaces.

It is just a very difficult job to totally replicate the very smooth and proportioned flow of a single surface.

So even in the future when that tool becomes available, I would still really recommend building surfaces in larger pieces when possible, as shown above. It will always be the most reliable way to ensure smoothness.
