Hi guys, I want to create a facade for a building. Because of the concept I want it to have something to represent music. So I thought of the vibrations of the strings of a harp. Now I need to make these waves in dynamo. I already have a start where I divided the height of the building and populated it with line but now I want to change the shape of the lines. How would I do that? Would it be possible to change it 2 lines at a time? Any help would be greatly appreciated.Here is the dynamo file. I hope it works: Facade
