I just upgraded to 2014. When i open certain drawing files, the bend lines on the flat view are messed up. I've fixed them by going into that part and suppressing, then unsuppressing the bend lines. However, after saving the drawing, closing it, and reopening it, the bend lines get messed up again. It doesn't always happen to the same part in the drawing, so I can't find a pattern to what is going on. The drawing that I am working with have mutliple configurations of the same parts. Is there a way it is referencing the wrong configuration when the file opens? How can I keep this from happening so I don't have to fix the bend lines each time I need to update the drawing?
