I have two lines at a distance between them, one is straight and the other is an arc. I draw a loft-bend. The problem is that I need some continueing up and down. I thought that creating another twoo loft-bends and them joining toghether will solve the problem. As you see the up and down sketch are the same with the basics sketckes for the loft.

Can you give another solution for this problem?

Thank you!

I don't want to look like this. I want to be just one body in sheet metal.
