What type of drawing shows an object reduced or enlarged in size according to a specific ratio?

A scale drawing is specifically designed to represent an object at a reduced or enlarged size based on a specific ratio. This means that the dimensions of the actual object are scaled down or up to fit a particular size while maintaining proportion. For example, a scale drawing might depict a building where 1 inch on paper represents 10 feet in real life, thus enabling viewers to understand the dimensions of the building in a manageable format.

In contrast, a blueprint typically refers to a detailed technical drawing often used in building and construction, traditionally printed in blue. Although blueprints may include scale drawings, they are not solely defined by their scale. Technical drawings encompass a variety of detailed representations used to communicate the specifications and functions of objects, but they don't exclusively address the concept of scaling. A design sketch is usually a rough or informal drawing focusing on the conceptual layout and idea, rather than precise measurements or scaling, making it less suited for representing objects in specific ratios.
