Scale modeling is the practice of creating a smaller or larger version of an object, often used in fields like architecture, engineering, and hobbies. These models are built to a specific ratio, allowing for detailed representation while maintaining proportions. For example, a 1:100 scale model of a building would be 100 times smaller than the actual structure. Scale models can be made from various materials, including plastic, wood, and metal. They serve multiple purposes, such as visualizing designs, testing concepts, or simply for enjoyment in hobbies like model railroading or aircraft modeling.
