Isometric, Orthographic and Perspective, but perspective is not required to depict an object.

name three basic dimensions of orthographic drawing
An isometric drawing is a schematic detailing a three-dimensional object in an abstract space that has no vanishing point. So, you can see the thickness of the object, but all sides remain parallel, unlike how objects appear in real life. In real life, the sides of an object converge as they get farther and farther from the eye. Think of a building whose sides slope into a point off in the distant horizon. These drawings are helpful in giving precise measurements, scale, placement and proportions. A good example of an isometric drawing would be the assembly instructions that come with a piece of household furniture.
Shop drawings usually refer to drawings made by an engineer and distributed to the shop floor to be used by the fabricators. An as built drawing can mean one of three things. A) As built commonly refers to an item that will have a mirror or opposite part, and is usually labeled as Right or Left Hand, or Opposite Side. In this case AS DRAWN or AS BUILT means the fabricator is to make the part just like the drawing. Often these drawings are enlargements of sections of another drawing. B) The drawing is made during the building process. This would occur during custom building or prototype stage of manufacture. These drawings would then be sent to the engineer for finalization, assuming they work. C) The drawing is made from an existing sample part or product, sometimes by the engineer and sometimes by the people on the shop floor.
ISOMETRIC drawings are drawn at 60-30 degree angles. Orthographic projections are views of a 3D object, showing 3 faces of it. The 3 drawings are aligned so that if the page were folded, it would create part of the shape. Also called multiview projections. The 3 faces of an object consist of its plan view, front view and side view There are 2 types of orthographic projection which are 1st angle projection and 3rd angle projection.

An isometric is more specific
An orthographic drawing is one that uses a sort of perspective that does not portray an object the way it would look in a natural space. It shows each side of the object as flat and parallel to the "picture plane." It's not too unlike cubism. (Braque and Picasso explored drawing people and object by showing all sides at once.) This is used in order to give accurate engineering/mathematical dimensions. It is used for the fabrication of mechanical parts, furniture...
you are creating a multi demensional figure.
One technique used by drafters is that of multi-view drawings, which show an object from different viewpoints. Three views are common, but some simple structures only need one, while complex ones need four or more.
