I do a lot of UI/UX design in Illustrator. Often, I find myself needing to create different screens with slightly different elements (e.g. an open hamburger menu/a modal. something like below). I’ve been resorting to simply copying the whole artboard with all elements, however drawback is that it doesn’t update if I change the first screen, and creates a ton of duplicate items. What’s the best solution for this?
Create your first screen, and drag the art to the Symbols Panel. — Or drag the individual elements to the symbols panel. Symbols act sort of like “master elements”. You can then edit the symbol once, and see all other instances update.
