How does this translate into a design? These dimensions are used by a drafter to accurately represent the structure shown in a plan. A “scale” is also a ruler used in drawing and measuring architectural and engineering plans.

## What is the purpose of using scale drawings in construction?

Depictions are typically drawings or physical models. Drawing accurately to scale, and being able to shift between scales, is a fundamental skill of architectural drawing and spatial design. Scale drawings are used **to illustrate items that it is not useful or convenient to draw at their actual size**.

## What scale is used to draw plot plans?

Traditionally, interior plans are drawn at **quarter-inch scale**, which means a quarter inch on paper is equal to one foot in real life.

## What does scale 1.50 mean?

1:50 is a ratio. it means you’re **scaling 1 unit to 50 units**. that could be inches (1″=50″) or miles (1 mile=50 miles) or anything else, but it’s a direct scale.

## Which scale is generally used for building drawing?

Referred to as **1:10, 1:20, 1:30**,1:40, 1:50 or 1:60 scale. Typically in civil engineering applications, 1:10 (1″=10′) is used exclusively for detail drawings. 1:20 and 1:40 scales are used for working plans.

## How do you convert scales to drawings?

**Converting using a scale factor**

- To convert from a scale drawing to real life, measure a line in the drawing and multiply it by the scale factor to find the real length.
- To convert from real life to a scale drawing, divide the real life measurement by the scale factor.

## How do you determine scale size?

To scale an object to a smaller size, **you simply divide each dimension by the required scale factor**. For example, if you would like to apply a scale factor of 1:6 and the length of the item is 60 cm, you simply divide 60 / 6 = 10 cm to get the new dimension.

## What is the scale of 1 25?

Well, 1:25 means that **1 ‘unit’ on the plan is 25 ‘units’ in real life**, so 1cm = 25cm, 1ft=25ft etc.
