I'm currently trying to bend a metal sheet that already has bends on it, no idea how to do it, i've been using solidworks for around 3 weeks now. Any help would be much appreciated. I basically need the metal sheet with bends on it to be like the second image here on this link https://imgur.com/gallery/9n9OJfY

Ive tried to unfold the piece and doing a sketch bend but i keep getting error: Sketched bend cannot be created using a sketch that crosses other bends.
