A three-view drawing is also known as what type of projection?

A three-view drawing is referred to as an orthographic projection. This method involves creating a representation of an object by displaying it from three different viewpoints—typically the top, front, and side. The key aspect of orthographic projection is that it enables precise, scaled drawings without perspective distortion, making it a common technique in technical and engineering drawings.

In an orthographic projection, each view is aligned to show the object’s dimensions accurately in two dimensions, allowing for a clear understanding of the object's shape and size. This approach is particularly useful in design and manufacturing, as it conveys critical information about the object without any visual ambiguity.

Other types of projection, such as isometric, perspective, and axonometric projections, serve different purposes and present objects in distinct ways. However, they do not focus on accurately laying out multiple views as orthographic projection does. Thus, the three-view drawing format is strongly aligned with the principles of orthographic projection in conveying the comprehensive details of an object's geometry.
