How do you orient views and make section views

I feel like I'm coming here every day to ask you questions about simple functions, but I'm really getting tired of not being able to do anything.

I watched a bunch of videos on how do do section views, and I think I've got a good feel for it, except they only showed how to make projected views, not standalone views. But then I figured out I can break the association of a projected view and change the scale, so it basically becomes a standalone view. I also mostly figured out how to do a crop view.

But I'm still having a couple of problems. The drawing shown is what i'm trying to achieve.

If I do this projection/section view, it goes off at an angle, like an auxiliary view. As I mentioned, I can break and rescale it. But I want it oriented horizontally. How do I do that?

I tried making a section view in the model, but it doesn't... save? With the section? When I create the section view, it gets a name. That name shows up when I try to insert the view on the drawing, but I can get that orientation to come in, but there's no section. That's got to be a simple thing I'm missing.

When I try to create that saved section view, I can't orient the model "horizontally," only vertically. When I do the Orient "normal to" command, it chooses which side is up. I tried this:

With this method, the first face you choose is parallel to the screen and the second face you choose is at the top of the view.

1. Hold down Ctrl and select two planar faces. The second planar face cannot be parallel to the first.
2. Click Normal To (View Orientation flyout – Heads-up View toolbar).

But it doesn't work that way. I made a plane that I want to have parallel to the screen/paper. But when I... it just doesn't work. And that first sentence doesn't even make sense. Should I replace the word "at" with "facing"? The second plane I select always faces right.
