I am attempting to model a sheet metal part that has a hem that is then bent 90°. The quick sketch below should explain what I am attempting to do.

Below is the best that I have been able to do. I add a hem and then use the "Sketched Bend" feature after drawing a sketch line across the face of the part.

Attached is a sample file. SW 2014 Premium x64 SP0.0

Any help is much appreciated!
