How do I revolve an ellispe shape?

Hello, I've been trying to create a shape which would link the five vertices in the attached shape, which would make a half-ellipse, however I cannot find any method to create the desired shape. Could anyone help me create a surface between the five points?
I've attached an image and file link, and if anyone needs help understanding my problem before they can help me, I can try my best to clarify.

You shared via link only, so I can't copy it to help model the solution. In this case, I would try a fill surface with the perimeter of sketch 1 as the edges, and the two arcs in sketch 2 and 3 as guide curves. You can then make a flat surface with the offset surface tool and sketch 1. Boolean/Add the two surfaces together to create a solid.[edit - it is public, I just wasn't logged in. working on a example now]
Turned out that fill was fussy and I could only get it to work if I used sampled guides, which then produced lumps. Instead, a loft with a guide worked.
Bear in mind that the ends of this shape are degenerate and NURBs surfaces don't really like to do this. It works at this level, but if you need to shell it or make offsets, etc. you may run into issues.
