Models are an eficient method for exhibiting and selling a design. Many people, including developers and would be house buyers, cannot visualise a design in three dimensions (3-D) from two-dimensional (2-D) drawings. An architect may employ smallscale
physical models, or digital computermodels, to help explain the ideas.
A model may be useful in explaining a complicated or unusual design to the building team, or as a focus for discussion between the design teams such as architects, engineers and town planners.
Models are also used as show pieces, for instance as a feature in the reception of a prestigious building, or as part of a museum exhibition (for example scale replicas of historical buildings).
