Orthographic Projection “COPY” Orthographic Projection

Representational drawing and sketching: Is concerned with "drawing what you see," or "drawing that which you imagine as if you actually saw it." *(Sketch of garden shed) “COPY”

Technical drawing: “COPY” Is concerned with representing objects according to drawings that allow for: Size, proportions, and structure - as well as appearance - to be shown. The most basic concept involved is the geometry of "projection." “COPY”

An orthographic projection drawing - since it is a "flattened single view" of a (3-D) 3 dimensional object - is an "exactly sized" representation of the real object on a 2 dimensional surface (paper) AS SEEN IN THAT VIEW.

** Name these views: (6)

*This process is called orthographic ("true drawing") projection. “COPY”

*It also works in reverse: “Don’t copy” a) If you correctly draw the individual views b) Fold them all up into a box with 90 degree corners c) Then project the corners of each drawing into the middle of the box the intersections of those lines will define the 3 dimensional object.
