Thumbnail Sketch A preliminary visual of a possible idea for a design. Most thumbnail sketches are not full size and have little detail. Their purpose is to help quickly explore possible alternative designs.
Isometric Sketch 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.
Multiview Sketch 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. An isometric sketch of the object is often included.
Orthographic Projections A method of representing views of a three-dimensional object by projecting the visible faces in each view on a two-dimensional plane.
