Trying to replicate the image pattern below. I am currently using a long rectangle shape and adding anchor points which I can then get the zig zag in areas I want but not sure how to smoothly go from the zig zag to the wave pattern seamlessly. I've tried using 'smooth' under zig zag but then I can't move the wave positions directly over the zig zag points. Wondering if there are any tutorials or advice on achieving this same outcome. Still learning Illustrator so any advice is appreciated.
