I am new to this sheet metal stuff. We don't have much need for it, but we do have an occasional bent plate, here and there. So, I made a new part, converted to sheet metal, and all was right with the world, nice flat pattern, as expected. So, I go to the actual drawing where the sheet metal part is needed, use the same profile, extrude, convert to sheet metal, specify all the same parameters...no flat pattern. I'm sure I missed something, so can someone here help? See attached.
