So I am very new to working with sheetmetal in solidworks. I am trying to take a flat pattern and make two bends in it. However, there are some areas which I intentionally would like to remain straight. Based on the way it is drawn, there are relief cuts which in reality when putting it on a press brake, will create sections which remain flat, however when I try to bend this in solidworks, the whole part bends along that line. Is there a way to select certain areas of the flat pattern to remain unbent? I have included one picture of the part I am having issue with, and a picture of how it should look.
