What is the purpose of scale in construction drawings?

Scale drawings are used to illustrate items that it is not useful or convenient to draw at their actual size. In the construction industry, a range of scales are generally used depending on the nature of the drawing.

What is scale drawing?

A scale drawing is a drawing where the dimensions are proportional. to the actual size of the object being drawn in a predetermined ratio. In plain English, a scale drawing is a drawing which has been reduced or enlarged from its original size, to a specified scale. (Defined by Collins English Dictionary).

Why do we use scale in drawing and map?

A map cannot be of the same size as the area it represents. So, the measurements are scaled down to make the map of a size that can be conveniently used by users such as motorists, cyclists and bushwalkers.

When would you use a scale drawing in real life?

Since it is not always possible to draw on paper the actual size of real-life objects such as the real size of a car or an airplane, we need scale drawings to represent the size like the one you see below of a van. In real-life, the length of this van may measure 240 inches.

What are the types of scale drawing?

Types of Scales in Engineering Drawing

Plain Scale.
Diagonal Scales.
Comparative Scale.
Vernier Scale.
Scale of Chords 1. Plain Scale Plain scale is cleanly a line which is separated into a proper number of equal parts, first of which is further sub-divided into small parts.

What scale is used for a section 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. 1:60 is normally used only to show large areas of a project.

What is an example of a scale drawing?

Maps and floor plans are some examples of scale drawings. The scale tells us what some length on the scale drawing represents in actual length. For example, a scale of “1 inch to 5 miles” means that 1 inch on the drawing represents 5 actual miles.

How do you interpret a scale drawing?

The scale is shown as the length in the drawing, then a colon (“:”), then the matching length on the real thing. Example: this drawing has a scale of “1:10”, so anything drawn with the size of “1” would have a size of “10” in the real world, so a measurement of 150mm on the drawing would be 1500mm on the real horse.

What is the purpose of the scale?

The scale is used to represent the relative distance in both horizontal and vertical directions.

What does a scale of 1 20 mean?

What does a 1:20 scale mean. The same goes for a 1:20 scale, which when used, represents a subject at a size 20 times smaller than its real word dimensions. For example a drawing drawn to a 1:20 scale would require a lot more intricacies than a 1:50 and 1:100 drawing.

Which is the best definition of scale drawing?

Definition of. more 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.

Can a percentage be used to scale a drawing?

Being able to scale drawings up and down using percentages has become very useful too. Working in Adobe (Photoshop, InDesign etc), you will find you can adjust the size of an object using a percentage, which is great if you are wanting to accurately scale a drawing up or down while working in photoshop while maintaining a precise scale.

Do you have to change the scale of a drawing?

So, if you scale or magnify a paper size accurately, it does not mean that you will retain an accurate (or standard) scale of the drawing. So, if you want to increase the scale of a drawing using a photocopier, but want to increase it to a standard scale (1:10 for example) then you must use the percentage factors for converting scale.

What is the purpose of a scale ruler?

An Architect’s or scale ruler is designed for use in determining the actual dimensions of a distance on a scaled drawing. Most architectural, construction and engineering drawings and blueprints are scaled to allow for large areas, structures or items to conveniently fit on a reasonable size of paper.
