City Line Generator is an add-on that creates outlines of modern cities with tall towers. It adds a new menu item under the Object menu. The add-on includes an operator box where you can customize parameters such as the length and width of the city, color variations, maximum and minimum tower heights, tower density, and tower size.

This tool is useful for creating background cityscapes for 3D environments, 3D data visualizations, or data comparison videos. It generates the initial city structure with default settings, which can then be adjusted according to your project's needs.
