Sheet metal adding a Knee/darting ?

[RedNova1]

making a bracket that has to look like the attached .step file in sheet metal design with Inventor 2012.
I have made the bracket minus the knee on the top of the bracket does anyone know how to add this to a sheet metal part and still allow it to unfold?
I can model it in with sculpt but well not unfold then...
Any advice would help me out huge, thank you all in advanced.

Are you talking about the corner rib? If so, this will not flatten with Inventor as material deformation occurs in more than 1 direction. That is a stamped feature.
Here are some ifeatures that should work for you..
