A model is more credible than a drawing

Relationships among objects are more easily comprehended

Because it provides more information in a format that is more readily comprehended than a drawing, a model can’t help but appear more credible. What’s more, because a model conveys information spatially, it connects with the observer in ways that drawings simply cannot.

Elevation drawings exist solely on a two dimensional plain and do not provide any information about how the spaces described actually relate to each other, as exampled on the left. On the other hand, a 3D model can represent any elevation with a perspectival representation, thereby providing a visual sense of how spaces described in a building's elevation actually relate to each other. As exampled above, you may not have known about a stairway leading to an upper mezzanine by simply looking at the traditional two dimensional drawing. Sure, there are stairs - and yes, there are doors - but the drawing fails in giving any true indication of their relationship. The 3D Model of the very same building instantly provides elevation data and clear visual representation of spatial relationships - saving your project time and, ultimately, money.
