So I am trying to create a sheet metal part with a 90° bend on all 4 sides. When I try to create the sheet metal part, it wont allow me to do the bends the way I need them. I tried creating the solid first, then converting it to sheet metal, but to get it to how I want it, I need to position the solid in a way that creates a "zero-thickness" error. My question is now, is there a way that I could take an already drawn flat-pattern drawing and import it in as the flat pattern for a sheet metal part. I've attached the pre-made drawing of the part I am trying to make.
