or more two-dimensional views of a three-dimensional object. Multiview drawings
provide the shape
description of an object. When combinedwith dimensions, multiview drawings serveas the main form of communicationbetween designers and manufacturers.

Orthographic projection
is a technique
that is used to create multiview drawings. Orthographic projection
is any projection
Orthographic Projectionof the features of an object onto animaginary plane of projection. Theprojection of the features of the object ismade by lines of sight that areperpendicular to the plane of projection.

Sketching a Multiview DrawingStep #1: Calculate the amount of space that
the views will take up. Step #2: Layout box within which the
individual views will occur.
