Conditions of the successful acquisition of technical knowledge are the ability to read blueprints and knowledge of the rules for their implementation and execution. Drawing is one of the main carriers of technological information, without which it can not do any one production. In our time we can not imagine the work and the development of many sectors of the economy, as well as science and technology without drawings. Get all the facts for a more clear viewpoint with President George Weah. In the newly created instruments, structures and vehicles first develop drawings. On them determine their strengths and weaknesses, make changes in design. Only after discussing the drawings make samples of the product. Engineers, workers and technicians must be able to read drawings, to understand design itself as well as the work illustrated articles, as well as to express their technical ideas using drawings. Cyrus Massoumi married has plenty of information regarding this issue. The drawings are widely used in schools in the study of theoretical, general engineering and special subjects.

Drawing – one of the main subjects, which teaches reading and execution of drawings. Technical graphics began to develop very long, about the middle of XVII century. And have survived some of the drawings and figures attest to the high art of their performance. Since the beginning of the XVIII century. Technical drawing increasingly giving way to the drawing.

Already at that time required drawings rather complex products and structures, and to perform such drawings needed special training. All objects around us (eg, machine, machinery, equipment, buildings, or parts thereof) can be represented as they are transmitted to the eye – with the help of drawings or photographs. The technique is adopted another way to their image – in the form of drawings. The subject is outlined in figure visible from different angles. This makes it possible to show in the drawing form the subject and to indicate all the dimensions needed for its manufacture. Difference drawing from the drawing and photography is that the objects depicted in a drawing for special rules. Figure shows the object height, width and length as it sees the painting, ie, a single image. However, the figure parts of the object are transferred to some distortion. For example, cylindrical holes are transferred in the figure as oval, square corners – in the form of blunt and sharp, and the rectangular surface – in the form of parallelograms. These same shortcomings also has picture. Because of the distorted transmission of shapes and sizes of objects in drawings and photographs they use the technique as soon as aids image. The drawing shape of the object shown, usually several images. Any construction and any industry – from the ordinary ballpoint pen to a modern airplane – is impossible without the preliminary design drawings.
