I have a relatively simple V shaped sheetmetal part that I am detailing. I placed the flat pattern on the sheet and then created a couple of projected views. I then changed the projected views to be the default formed views. As the sheet also has a lip on the sheet I placed a section view on one of the legs placing the cut plane perpendicular to the leg. The view appears to be created and the view label is created but there is nothing in the view. I was able to create the desired view by creating a new parent view and sectioning that so I guess the problem has been solved, but, I was wondering if anyone knew why the original projected view would not provide the same results.
The file is attached.
