I am designing a simple sheet metal part that requires four bends. When I import the flat view into a drawing the bend lines do not show up. I am familiar with the fact that the sketch setting must be turned on and it is for both the model and the drawing (in both the default configuration and flat view). Also, in the design tree on the drawing for the flat view the bend lines are set to "show" and not "hide". Is there any other setting which may be causing these lines to not show up? Thanks in advance.
