Blueprints are detailed architectural drawings that provide a visual representation of a building or structure. They include important information such as dimensions, materials, and construction methods. Blueprints serve as a guide for architects, engineers, and builders to ensure that the project is completed accurately and efficiently. Typically printed on large sheets of paper, blueprints use a specific color scheme, often with white lines on a blue background. This technique, known as cyanotype, allows for easy reproduction of the plans. Blueprints are essential in the construction industry, helping to communicate ideas and specifications clearly among all parties involved in a project.
