Thick wavy lines running parallel like train track - Do you know how to recreate this graphic?
Hi!
I'm trying to recreate the following waves.
The first one I managed to recreate with the zig zag (smooth) function, but as soon as there are more curves that run parallel to one another, I can't seem to make it work anymore. The curves / waves should be running like a train track, where the inner waves are adjusted to remain parallel with the outer waves. Right now they are the same size and therefore will run into one another in the corners - see my failed attempt below. Adjusting the zig zag size does not seem to work due to that it doesn't allow me to only slightly adjust it (e.g. setting 1.5 will automatically round up to 2).
Does anyone know how to recreate these images?
Thanks a lot!
