The Drawing Scale

 The whole idea behind creating scale drawings it 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 is 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 is 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 is 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 is to Four"

QUARTER SIZE or 1 millimeter on paper= 4 millimeters on the drawing.

The drawing is one quarter the size of the artifact.

I've decided to post this because in our last drawing plate, we got confused on how we should write the scale 0.75:1. Click HERE if you want to take a look on my first drawing plate for this semester. I got an 85 for it. It's too low. Sad.
