looks interesting so gave it a go. Used a lofted bend between two end profiles, relief cuts are funny though and depending how you are to form could be removed while flattened.

Hello Ned! Thanks a lot for your good suggestion. One thing is that in the original part there is a curved edge of that cylindrical formed shape. in the sheetmetal loft feature there is no center line or guided path option to generate a curved path. So my question is that how can this curved edge can be generated according to this sheet metal part? Here I attached the 2D CAD drawing which is a side view of that part.
