Is there a way to only bend a section of a sheet metal part?  I'm new to them but it seems to be the only practical way to make this part. As you can see, the bend keeps messing with the top section, which is supposed to be flat.  The angles, bend radius, and width of the "legs" are correct per the drawing, and I can not figure out how to only bend the legs down without affecting the top. Any help is greatly appreciated.
