Surfacing Issue

Hi all,
I'm re-creating and cleaning up some legacy CAD (in blue below), and I'm stumped as to how to patch the missing U-shaped surface. A fill doesn't transition nicely to the surface off to the right.
Any ideas?
Thank you!

I actually figured it out - the fill worked just fine in the end. When it hadn't been giving me clean results previously, I'd been starting the fill at the beginning of the half-circle, not halfway back the flat.
Also, not sure if this was a factor or not, but I now selected the edges of the fill sequentially. I think before I may have started by selecting opposite ends, and then selecting the connecting edges, as you might for a loft.

The order of selection shouldn't matter for fill. It does get picky if there are microscopic gaps or if the edges don't all join at vertices. Sometimes it can handle that, but it gets confused.
As you've found, it's best to limit fill to the complex areas, and if it's really obvious what you want, to build the most straightforward way without fill.

I can see the part, but can't copy it to really work on it. You'll need to make it fully public, not a link share.
In general a fill surface should be able to do this, depending on how you constrain and guide it.
