Can Drawings Distort the Truth?

USE: What buildings and spaces will be used for

AMOUNT: How much would be built on the site

LAYOUT: How the buildings and public and private spaces will bearranged on the site; and the relationship between themand the buildings and spaces around the site

SCALE: How big the building and spaces would be, their height,width and length

LANDSCAPE: How open spaces will be treated to enhance and protectthe character of a place

APPEARANCE: What the building and spaces will look like, for example,building material and architectural details

Summary:

All drawing conventions give rise to their own inherent perceptual distortions, it just depends what you are used to seeing

Orthographic Projection

Multi-view Drawings: The Principal Face in Each View is Orientated Parallel to the Picture Plane.

Axonometric Projection Isometric: The three major axes make equal angles with thepicture plane.

Dimetrics: Two of the three major axes make equal angleswith the picture plane.

Trimetrics: The three major axes make different angles withthe picture plane.




Isometric: projection of a three-dimensional subject, inclunedto the picture plane in such a way that its three principle axesmake equal angles with the picture plan and are equallyforeshortened.

Dimetrics:projection in which two of the principle axes areequally foreshortened and the third appears longer or shorterthan the other two.

Trimetrics: projection in which all three principle axes areforeshortened at a different rate.

Axonometric Projection




Oblique Projection

Elevation obliques: A principle vertical face isorientated parallel to the picture plane.

Plan obliques: A principle horizontal face isorientated parallel to the picture plane.




Perspective Projection One Point Perspective: One horizontal axis isperpendicular with the picture plane, the otherhorizontal and the vertical axes are parallel with thepicture plane.

Two Point Perspective: Both horizontal axes areoblique to the picture plane, and the vertical axisremains parallel with the picture plane.

Three Point Perspective: Both horizontal axes as wellas the vertical axis are oblique to the picture plane.




One Point Perspective projection portrays a three-dimensional form by projecting all of its points to apicture plane by straight lines that converge at a fixedpoint representing a single eye

Perspective Projection

Two Point Perspective projection more closely mimics abinocular image.
