Scale models are miniature representations of real objects, designed to accurately reflect their proportions and details. These models can depict a wide range of subjects, including buildings, vehicles, and even landscapes. Scale models are often used in various fields such as architecture, engineering, and hobbies, allowing for easier visualization and planning. The scale of a model is typically expressed as a ratio, such as 1:100, meaning the model is 100 times smaller than the actual object. Enthusiasts often create scale models for model trains, aircraft, or cars, using materials like plastic, wood, or metal to achieve realistic appearances.
