I'm not sure if this should be a sweep or a loft. I am modelling a piece of tin that will be welded to the top of a battery at point A. At point C, this strip of tin should be parallel to the angle datum I show below. Therefore, what I'm looking for is no twist between points A and B. Then, I want the angle of twist to change from theta = 45 degrees to theta = 0 degrees. How do I do this?

Thanks in
