Steve, you can model this type of part with either the PartDesign or GSD workbenches by using the Multi-Sections tool. One method would be to make a Multi-Section Surface between the 135 deg bent section and the flat section with tangencies, and then use ThickSurface to make a solid with thickness. (let me know if you need more details)
I don't think the Sheetmetal workbench will work for this part, because it only works with constant bend angles and you have a varying angle. Maybe someone else might be able to tell us otherwise.
You could use the hopper tool from the Generative SheetMetal Design Workbench to give you varying angle however in V5R14 I was only able to generate half of the plate you require...Maybe V5R16 will do the whole profile
