Study Notes

Orthographic Projection

A type of projection that presents a 2D representation of a 3D object, showing the object's dimensions and shape in a single view.

Key Characteristics

The obverse of an orthographic projection is the reverse view of the object.

Non-Parallel Projection

If the principal planes or axes of an object in an orthographic projection are not parallel with the projection plane, the depiction is called an oblique projection.

Parallel Projection

The principal axes or planes of the subject are parallel with the projection plane in orthographic projection when the object is viewed directly from the front, top, or side.

Axonometric Projection

Also known as parallel projection, it is a type of orthographic projection where the object is rotated to show multiple sides simultaneously.
