If the option of rotating Artboard is too difficult in Illustrator, maybe it is easier to create "rotated views"?
When working with packaging, the inability to rotate the view of the packaging walls while working in one document is really a prehistory of creative work. In a professional program, this must be resolved by the Adobe Customer Support Team.
Thank you everyone for the current effort. Best Regards
