How to read the blueprints?
If it happened that you had a sharp question, how to read the drawings, and do it professionally and correctly, then most likely you will have to spend some time on training. The long journey will be lined up in front of you in the form of reading a huge amount of often unnecessary literature, clicking on the Internet links of textbooks and the like.
A short version of how to learn how to read drawings is presented in direct work with the drawings under the guidance of an experienced engineer. For some people, at least a few people familiar with the construction field, it will be sufficient to familiarize themselves with the GOST standards, the electronic version of drawing up the drawings or the “Teaching for Dummies” tutorial. The main thing for a correct understanding of the drawing remains the same indicator - to have excellent spatial imagination, otherwise no knowledge and experience will bring the proper result.
The ability to read blueprints is necessary for a number of construction professions: fitters, estimators, bricklayers, concrete workers, sometimes installers, welders, and so on.To understand how to read the drawings, first of all you need to work directly with them. If you do not have a corresponding higher education in industrial or civil construction, then to read a drawing you need to know the established standards, rules, conventions and simplifications that are specific to the area of interest to you (drawing details or drawing a country house). General rules to help understand the essence of how to learn to read the drawings are:
- Introduction to the caption of the drawing. It is her study that allows you to find out from which material the part shown is made, its name and scale of the drawing.
- The designation of images that served as the prototype of the presented details of the drawing.
- Analysis of the drawing image. It is the representation of the shape of the product or part that helps to better understand the essence of the data entered in the drawing. If it is impossible to recreate the whole part in your imagination, try to divide it into several parts and present their geometric shape.
- When you imagine a product or object model, you can already study its dimensions (exact value) in the drawing.
Studying the drawing helps to familiarize yourself with the name of the product, how many parts are necessary for its manufacture, calculate the scale and dimensions of the product, its mass, carefully review the parts shown there, which help to more accurately present the future configuration of the product in its finished form, taking into account all the necessary requirements and standards .
In order to always have access to information on standardization and technological requirements necessary for the chosen industry (building a house, pipeline, manufacturing parts, structures, etc.), it is worthwhile to have a reference book or textbook containing this information for personal use. You can also print data from the Internet so that it is always at your fingertips.
Summarizing all the above, the reading of the drawing should begin with an introduction to all its types, rules and methods for applying products of various shapes and sizes to the paper plane. Remember the conventions and standards necessary for the correct exposure of the drawing when it is compiled.
