1.-DRAWING

When you want to describe objects that have not yet been created, the words are insufficient. For this reason, graphic expression is so important in the technological world. Graphical expression simplifies the communication of some concepts related to the topology and geometry of objects. To draw you need paper, pencil and drawing instruments, among which the square, the bevel and the compass are highlighted. The passage of objects from 2 to 3 dimensions is called perspective. In order to universalize the graphic expression, standardized perspectives are used, among which the European system stands out. The European system represents the objects by means of an orthogonal projection in the planes of the space. Each projection is called A view. The most representative is the elevation, under it is represented the upper floor and to its right the left-hand profile of the objects. To express their dimensions are used the dimension lines that express the actual values of the objects in millimeters. The sketches of the objects are their representation in the European system by freehand and with their main dimensions. They can be set sketches or can be exploded. Both drawings are related by numbers called marks.
