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. Common examples include model airplanes, train sets, and architectural models. Scale models serve various purposes, such as visualizing designs, testing concepts, or providing a tangible representation of ideas. They can be made from materials like plastic, wood, or metal, and often include intricate details to enhance realism. Enthusiasts enjoy building and collecting these models as a creative outlet.
