I have created a model of a small catch tray that I would like to have built. The machinist says that he wants the flat pattern view of the piece. When i created it, it looked fine. I had dimension it and prepared it. Then I opened the assembly drawing that it was a part of and closed it. The next time I opened the flat pattern view it went back to a folded view and removed my dimensions. I am not concerned about the design of the tray, only how to get the tray to stay in a flat pattern view in the drawing. Below are the assembly drawing, part drawing and part. The problem i with the trough, the brackets are only there so that you can open and view the assembly files.
Any help will be greatly appreciated.
