If they did not their drawings would be the same size as the structure that they are building which would make it impossible to work with them!
Infinitely many. You can represent any distance in real life by 1 unit on your scale or, conversely, you use any distance on your scale drawing to represent a unit of length in real life.
A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount (called the scale). The scale is shown as the length in the drawing, then a colon (":"), then the matching length on the real thing.
A scale drawing!
The scale.
The scale factor.
it depends of the scale of the drawing
It shows the constant of proportionality between the scale drawing and the real-life object.

The "scale" of a drawing is its relation in size to the inspiration. So, for example, if you were drawing a picture of your friend, and it was half the size that she is in real life, the scale would be represented as a ratio of 1:2.
It matters check the proportional dictionary and see that
It is a scale drawing

The scale factor of a scale drawing is the ratio of any length in the drawing to the true corresponding length in the "real" object.
