Perhaps someone can enlighten me before I pull my hair out. I have a simple sheet metal cylinder for a part which flattens out fine. In the drawing, from the view pallette, the flat pattern option shows (see attached) but with no lines. If I continue to drag it on the drawing, I get the bend line info with NOTHING else and get an error relating to needing to use isometric dimensions. Baffled. Never had this happen before. I was figuring maybe an option got turned on for hiding lines, etc. but nothing jumps out. Thanks for any info!
