The "Extrude along path" technique is a very powerful modelling tool. It consists of creating a surface by sweeping a given profile along a given path.
路径挤压’技术是一个非常强大的建模工具。它通过由给定的轮廓线沿着指定的路径伸展，就能创建一个面。

The modelling for this image is quite simple because it's essential made by profile extrusions for skyscrapers and by subtractions for Windows.
