See screenshot below.
I need to toggle the checkbox to "Display sheet metal bend notes" Why are all these options now grayed out?
The Flat Pattern view you are editing is a projected view that was changed from the formed configuration to the flat pattern.
Drag a new flat pattern view from the view pallet on to your drawing.
You will be able to turn on bend notes with this view. You will have to flip the orientation of the flat to match what you need.
I've played around with a few different things on one of my sheet metal drawings and can't replicate it. What version and SP are you on? Can you attach the drawing and part file?
I'm on 2018 sp3.0
I'll try to attach the files here. It is happening to a co-worker of mine also.
I had just attempted to do the same thing by dragging in a new flat pattern and it worked. I had not seen that the view was a projected view...
I believe it has to do with your flat pattern view being top view of a config named FLAT PATTERN as opposed to the actual flat pattern view.
You have a mixture of configs and flat patterns, but only one won't be grayed out. This one:
Flat pattern (yellow) was checked until I RC'd the view for the menu>Properties.
I don't have the time to decipher further, but hopefully, this will point you in the correct direction.
