Presentation transcript:

Drawing to Scale The whole idea behind creating scale drawings is to allow the drafter to create a drawing which is proportionately the same as the artifact it represents. Using a measuring device called a scale, we can create accurate drawings of both very large objects or very small objects and fit either on a standard size piece of paper. 2:1 Pronounced "Two to One" DOUBLE SIZE :2 millimeters on paper =1 millimeter on the artifact The drawing is twice as large as the artifact. 1:1 Pronounced "One to One" FULL SIZE: 1 millimeter on paper =1 millimeter on the artifact The drawing is the exact same size as the artifact. 1:2 Pronounced "One to Two" HALF SIZE : 1 millimeter on paper =2 millimeters on the artifact The drawing is half the size of the artifact. 1:4 Pronounced "One to Four" QUARTER SIZE or 1 millimeter on paper= 4 millimeters on the artifact. The drawing is one quarter the size of the artifact.
