Easiest way to "skin" these edges

[SJS66]

I'm trying to "skin" of "loft" these edges & faces, or make terrain from them somehow. I don't seem to be having much luck so far. Basically I want to 'skin' the curves joining the rectangle to the hexagon. Have attached file for anyone to play with.

Very quick with Curviloft.

Thanks Box, I knew Curviloft was the key. I haven't really used it much, as you could probably tell.
I tried several attempts with it but I was pressing the wrong button. I ended up using the old "join the dots method" but that is exactly what I was looking for. Just gotta press the right button. That is going to come in very handy.....the learning curve continues.
