Which aspect is communicated through orthographic views on blueprints?

Orthographic views on blueprints are specifically designed to communicate the shape and size of a part. These views present multiple two-dimensional representations of a three-dimensional object, typically from various perspectives, such as the front, top, and side. By doing this, orthographic projections provide precise dimensions and geometric details that are essential for manufacturing and assembly. This clarity in representation allows engineers and manufacturers to understand the form of the part being created and ensures accurate interpretation for machining or fabrication processes.

Other aspects like material durability, weight distribution, or color and texture are generally represented through different means in engineering drawings and specifications, such as material specifications, additional notes, or visual aids, rather than through orthographic projections.
