have user with sheetmetal..convert to sheet metal issue

Not a sheet metal expert, very rarely need it in my work.  i have a user that wants to convert a part to sheet metal, which i am not sure is possible, am looking for feedback if any one has some time, even if you tell me what an idiot i am for attempting this on this part .  Tried searching for a better understanding, but nothing in the books that is helping me much.

Thanks!
