Partial bend challenge

Hi there,

I am trying to figure out how to make a partial bend on a flat sheet. What I want to do is attached as a file SW2012SP4.

Using the Sketch bend command the desired result is not achieved because the bend line has to be from side to side of the sheet. What I want is the press brake to bend the sheet to 150deg open angle 3/4 of the sheet and the rest 1/4 of the sheet to be freely relieved to its original flatness.

Of course if it is possible I would also like to be able to get a flat pattern of the result because that partial bend shoult not be the only bend on that sheet.
