Before you begin to consider the standard scale of the drawings, you should understand what exactly is this concept. So, a similar value is generally a ratio of two linear dimensions. However, such an interpretation of this definition as the ratio of the size of a drawing to the dimensions of a real object is more widely known. Consequently, we can quite rightly assume that the above term has found wide application in cartography, geodesy, and, of course, design.
Why is this necessary?
As mentioned earlier, real objects can have quite significant sizes, and very small. However, a person cannot sketch everything in full size, because to display a building plan on a sheet of paper, a canvas of colossal dimensions would be required, and, in turn, to recreate small elements (such as in a clockwork) would require a high degree of detail. As a result, the person has adapted to depict the necessary objects, which are reduced (or enlarged) a certain number of times for ease of perception and the so-called "readability" of the picture. Currently, certain standards are in force, for example, GOST "Scale of drawings", which describe all the requirements for the form and content of the relevant images.
Large objects
As mentioned earlier, to display buildings and other large-sized objects, it is necessary to use the scale of the drawings of the so-called reduction. They are standardized, which means that random sampling will not work. The most common values are: 1: 2; 2.5; 4; 5; 10; fifteen; 20; 25; 40; fifty; 75; 100; 200; 400; 500; 800; 1000. Consider what a record of this kind means. So, the real (in other words, natural) dimension of an object is expressed as the inscription 1: 1. Therefore, when reducing the scale of the drawings, the initial size (1) is first described, and then a number that shows how many times the drawing is reduced in relation to real dimensions. In construction, in addition to the above standard records, 1: 2000 signs can also be used; 5000; 10,000; 20,000; 25,000; 50,000.
Small parts
In the event that small objects need to be depicted in the figure, the scale of the enlargement drawings is traditionally used. In this case, there is not such a wide variety of values, however, the standard stipulates the most commonly used values. So, the type range is as follows: 2; 2.5; 4; 5; 10; 20; 40; fifty; 100: 1. The decoding of such inscriptions is read as follows: first, a number indicating how many times the image in the drawing is enlarged compared to the original object. The second digit after the colon displays the real (it is - natural or real) size of the object in question (assumed to be 1).
Conclusion
This article examined the scale of the drawings and their standard series. It should also be noted that on the plans, projects and images themselves, the magnitude of the scale is indicated in a specially designated column in a frame, otherwise called a stamp.
