Need help converting to sheet metal

I've got 2 parts that I've created, that I have to get a flat pattern for, so I'm trying to get them converted to sheet metal. Most of the model is created using 3D Sketches, so I'm having no luck getting them converted. They probably have to be tweaked some to make the conversion, but I havent been able to figure out what needs to be done.

I've attached them, in the hopes that someone can help me out.

Files were created using SW2013. I've also uploaded a STEP of each in case that can be used for older versions of SW.
