Hello All,
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!
Somehow the Flat Pattern feature got deleted from the part. Delete the Sheet-Metal1 feature and then redo the Insert Bends. Once you do that you'll see an extra Flat-Pattern1 feature at the bottom. You might need to switch to the flat pattern configuration and unsuppress that feature.
