You have probably somehow turned off "rebuild attic walls", so, on the attic level, manually redraw the wall.

Did you delete the original house exterior wall, where the stairs meet the landing?

Auto Roofs build over rooms, including invisible rooms. In this case it may be necessary to build a 3rd floor with a low ceiling, and then add an invisible room. If you are inexperienced, this awning roof on an upper floor, will be difficult to do. However, building the awning roof over a window or garage door on the 1st floor (using an invisible room) will be easier to do. It would be easier for you to use a sloped soffit as the awning roof, on that 2nd or 3rd floor.

Do you think that if you open the bump-out room, and on the structure tab, raise the floor???

The reason your landing is not enclosed by any exterior walls, is because you have not built the exterior bump-out (walls) that are shown in the pic of the real house. Build the bump-out, and the landing will then be placed inside that bump-out.

If you create the tray using room divider walls, the framing will show.

You do not necessarily need Pro. It depends on the design. You need to post this in Q&A, as Rookie65 suggested. It would also be helpful if you post a floor plan jpeg image, and also a 3d jpeg of what you have created, and where the problem is.

floor Lanai ??????????

A custom backsplash is a vertical object, whereas a slab is a horizontal object. They are both shaped in the same way. Consult the reference manual or the knowledge base for how to shape them.

Of course I used landings. If you don't know how to shape a landing, look in your reference manual, or check the knowledge base.

However, if you're really dedicated...you could make the door panel glass, then add the custom backsplash as the opaque door panel, and then shape it around the vents. Lots of work.

You haven't said how you put it on the elevation view. Did you use a cad shape? If you use a custom backsplash, it will show in a 3D view, but of course it won't cut a hole in the cabinet.

After seeing pics of the real house, I modified the roof a little bit more.

It's all about elevation regions, and elevation lines. Keep experimenting until you get it right.
