Projection drawing

Projection drawing

The process or technique of representing a three-dimensional object by projecting all its points by straight lines, either parallel or converging to a picture plane.

axonometric projection

The orthographic projection of a three-dimensional object inclined to the picture plane in such a way that its three principal axes can be drawn to scale but diagonal and curved lines appear distorted.

cutaway

A drawing or model having an outer section removed to display the interior space.

diametric projection

An axonometric projection of a three-dimensional object to the picture plane in such a way that two of its principal axes are equally foreshortened, and the third appears longer or shorter than the other two.

exploded view

A drawing that shows the individual parts of a structure or construction separately, but indicates their proper relationship to each other and to the whole.

isometric projection

An axonometric projection of a three-dimensional object is created by having its principal faces equally inclined to the picture plane; so that its three principal axes are all equally foreshortened.

longitudinal section

An orthographic projection of a section made by cutting through the longest axis of an object.

oblique projection

A method of projection in which a three-dimensional object, having one principal face parallel to the picture plane, is represented by projecting parallel lines at some angle other than 90 degrees.

oblique section

An orthographic projection of a section made by cutting with a plane that is neither parallel nor perpendicular to the long axis of an object.

orthographic projection

A method of projection in which a three-dimensional object is represented by projecting lines perpendicular to a picture plane.

paraline drawing

Any of various single-view drawings characterized by parallel lines remaining parallel to each other rather than converging as in linear perspective.

section

An orthographic projection of an object or structure as it will appear if cut through by an intersecting plane to expose its internal configuration.

transverse section

An orthographic projection of a section made by cutting through an object along the shortest axis.

trimetric projection

An axonometric projection of a three-dimensional object inclined to the picture plane in such a way that all three principal axes are foreshortened at a different rate.
