A 3D presentation model may be useful in explaining a complex or unique design to the building team comprised of architects, engineers, and town planners. Models are used for visualization mostly and can be considered as best for presentation, displays as well as sales & marketing purposes, especially for brochures and flyers.

In the world of visualization, there is an increased emphasis on models that are acceptable representations of reality and are easy to comprehend. Models are an efficient method for explaining and selling a design of a product. Common people, including building developers and home buyers, cannot visualize a design in 3-dimension and rely on 2D traditional drawings so an architect may employ small-scale physical models, or digital computer models, to help them out in understanding their projects.
