Having trouble converting to sheet metal

Hello, SolidWorks people.

I have a part that I created from importing a DXF and then sweeping the profile along the path. I did this because I can't figure out how to draw it with sheet metal. I was thinking I could just do what I did and then convert it to sheet metal after, but that isn't working out for me. I'm assuming because there are three different radii on the part.

Does anyone have any insight on how I could draw this the real way (i.e. actually draw in sheet metal instead of trying to convert) or maybe might be able to explain how I can convert this into sheet metal?

Thanks in advance for your help.
