orthographic projection

n
1. (General Engineering) a style of engineering drawing in which true dimensions are represented as if projected from infinity on three planes perpendicular to each other, avoiding the effects of perspective
2. (Physical Geography) a type of zenithal map projection in which the area is mapped as if projected from infinity, with resulting distortion of scale away from the centre

orthograph′ic projec′tion


n.
a two-dimensional graphic representation of an object in which the projecting lines are at right angles to the plane of the projection. Also called orthog′onal projec′tion. Compare isometric (def. 4).
[1660–70]

orthographic projection

a rendering of an object or floor plan of a building in scale as viewed perpendicularly from above. Cf. isometric projection.
