1
A method of representing views of a three-dimensional object by projecting the visible faces in each view on a two-dimensional plane.
2
Observing the operation of a device and describing its function and design specifications.
3
A type of pictorial drawing in which vanishing points are used to provide the depth and distortion that is seen with the human eye.
4
A sketch in which an object’s parallel edges are drawn with parallel lines, typically at 30-degree angles to the horizontal baseline. There are no vanishing points and three sides of the object can be seen simultaneously.
5
A sketch typically including three primary views of an object that are drawn using orthographic projections. The top, front, and right primary views of the object are projected onto a drawing plane perpendicular to each view. An isometric sketch of the object is often included.
6
A change or improvement designed to produce optimal accuracy and function.
