Below is the latest screenshot of Eiffel tower as seen in Google earth. It is very clear and accurate model of tower. It is most probably made using Sketch up tool.
The purpose of posting this photo here is to give civil engineers a clue that everything is possible even in small tools like sketch up, when it comes to 3D building modeling.
It is to inform you all that sketch up is a free tool which can be used without any special skill or training.
