*3D Eiffel Tower models can be used for a variety of purposes, such as*: **Architecture and design:** 3D Eiffel Tower models can be used by architects and designers to plan and visualize renovations and additions to the Eiffel Tower. For example, 3D models were used to design the new glass floors that were installed on the second floor of the Eiffel Tower in 2019. **Engineering**: 3D Eiffel Tower models can be used by engineers to analyze the structural integrity of the Eiffel Tower and to identify potential maintenance issues. For example, 3D models were used to assess the damage caused to the Eiffel Tower by a storm in 2018. **Education:** 3D Eiffel Tower models can be used to teach students about the history, architecture, and engineering of the Eiffel Tower. For example, students can use 3D models to explore the different parts of the Eiffel Tower and how they work together.
