SCALE MODEL

A scale model is a representation or copy of an object that is larger or smaller than the actual size of the object being represented. Very often the scale model is smaller than the original and used as a guide to making the object in full size. Scale models are built or collected for many reasons.
Professional modelmakers often create models for the below professions:
For engineers who require scale models to test the likely performance of a particular design at an early stage of development without incurring the full expense of a full-sized prototype. For architects who require architectural models to evaluate and sell the look of a new construction before it is built. For filmmakers who require scale models of objects or sets that cannot be built in full size. For salesmen who require scale models to promote new products such as heavy equipment and automobiles and other vehicles. Hobbyists or amateur modelmakers make die-cast models, injection molded, model railroads, remote control vehicles, wargaming and fantasy collectibles, model ships and ships in bottles for their own enjoyment.
Scale models can also be objects of art, either being created by artists or being rediscovered and transformed into art by artists.
