Welcome to class!
In today’s class, we will be talking about the scale and scale drawing. Enjoy the class!
Scale and Scale Drawing
Scale drawing can be defined as the drawing of lines and objects to any given proportion or ratio.
In other words, it is the process of drawing an object to another size of its original size.
Types of scales
(i) Full scale:
This is the scale used to represent objects as they are or appear in real life or as it is given on a diagram. It is technically written as a ratio of n:n, where ‘n’ represents any number. E.g. 1:1.
(ii) Reduction scale:
This is a scale that is used to reduce the size of objects as they appear. It is technically written as 1:n, where ‘n’ could represent any number. E.g, 1:2, 1:10, 1:100, 1: 5,000,000.
(iii) Enlarged scale:
This scale is used to enlarge objects to be bigger than their usual size. It is technically written as n:1, where ‘n’ could represent any number. Eg. 2:1, 10:1, 100:1 100,000:1.
