Graphic Design

Condition for a successful mastery of technical skills 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 production. At the present time we can not imagine the work and development of many sectors of the economy, as well as science and technology without drawings. To the newly created devices, machines and facilities, 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 blueprints in order to understand as the design itself and the work submitted articles, as well as to express their technical ideas using drawings. The drawings are extensively used in schools in the study of general technical, theoretical, and special items.

Drawing – one of the main subjects, which teaches the implementation and reading blueprints. Technical Graphics has begun to develop a very long time, about the middle of the xvii century. And have survived some of the drawings and drawings show 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 were necessary drawings rather complex products and structures, and to perform such drawings needed special training. All objects around us (eg, machines, appliances, machinery, buildings or parts thereof) can be represented as they are transmitted to our eyes – with the help of drawings or photographs. The technique also adopted another way of their image – in the form of drawings.

Item passed on the drawing visible from different angles. This allows us to pass on the drawing shape object and specify all the sizes needed for its manufacture. Unlike Drawing from drawing and photography is what the drawing objects passed by special rules. Figure depicts the subject of its length, height and width so as to see him drawing, ie, the 1-meter images. However, the figure parts of the object are transferred to some how distortion. For example, cylindrical holes are shown in the figure as oval, square corners – in the form of blunt and sharp, and the rectangular surface – in the form of parallelograms. Same shortcomings owns and picture. Distorted due to the transfer of shapes and sizes of objects in drawings and photographs they use the technique only as aids to the image. On the drawing shape the object is passed, usually several images. Any construction and any industry – from the usual stick to the modern airplane – is impossible without a preliminary design drawing.
