Isn’t there a way to join the end faces of a closed-loop sweep solid without also losing the profile’s tangent edge visibility?
I just want to make a simple angle frame, without the seam at the beginning plane. But I don’t want to lose the visibility of the edge lines where flat faces join to curves, etc…
I though I used to know how to do this, but at some point, forgot, or the software changed or something…
Thanks!

Have you considered using a weldment instead?
Use the Merge Tangent Faces option.

But when I use “Merge Tangent Faces”, I lose the edge lines defining curve/flat faces on the profile…

No you don’t.

The only drawback to using Merge Tangent Faces is the fact that when using a circular profile, it will not recognize the outside face as cylindrical and therefore does not allow concentric mates. At least, that’s what happens to me because I haven’t been able to strike fear into Solidworks like matt can. 
You should be able to do that. Is there a special situation where it hasn’t worked for you? There are times when a sweep will convert analytical entities to splines, which would mess everything up, but I think if the path is lines and arcs and the profile is lines and arcs, you should be ok.
Sorry, I should have quantified that a little better. Using radii at the corners is when it doesn’t work.
The reason it doesn’t work is pretty simple; it’s because the entire outer face is now one entity instead of five in this case. I’m not saying there’s something wrong with the software, just pointing out a limitation with Merge Tangent Faces.
But I don’t want to lose the visibility of the edge lines where flat faces join to curves, etc…
WHY?
Yeah, you’re right. putting tangent elements in the path splines everything. In that case, I’d mate the path sketch.
Because tangent edges are easy to hook dimensions to in drawings.
Everything is about the drawings (for us)
A section view would be much more appropriate.
If it is all splines, you won’t be able to put dimensions on the section. Just don’t use the merge tangent faces setting, or put dimensions on the sketch.
Dimensioning to hidden silhouettes is poor form. I don’t do it and would not accept if it was being done for me.
If the section resolves as splines when it shouldn’t, there is a model problem that needs fixing.
