Why are 3d models better than diagrams

3D models are better than diagrams cause a diagram is flat, and its on a piece of paper, on the other hand 3D models have 3 Dimensions which show the model in a different view, they are also sometimes on paper but you have a better view if the model which helps you get more information of the diagram.

Hope I helped ya!! And plz put it under the right subject next time. This should go under Math.

Is there any answer choices?
