Definition of Technical Drawing

Discipline that deals with designing everyday items

A He drewis the figure, image or delineation that is usually done manually and with the help of a tool designed for this purpose, such as a pencil or a brush, on different materials, meanwhile, by technical, reference is made to that procedure linked to science whose mission is to obtain an end.

Then, once both concepts that jointly make up the concept that will occupy us have been clarified separately, we will say that the technical drawing is a system of graphical representation of different types of objects. The objective of this will be provide the most important and necessary information to analyze an object, help its design and enable both its building as their maintenance.

Almost all the objects that we observe on a daily basis and with which we interact were designed and built from a drawing that did not have as an intention to express art but rather the practical purpose of that object, what will it be used for, for example, if we are facing a tool.

Thanks to this specialization of drawing, the design of most of the elements that are around us is possible.

Have knowledge of geometry

The arrangement of geometric knowledge is essential when representing objects, without them it would certainly be unfeasible. Issues such as symmetry, angles, projections and magnitudes are very important to know in order to carry out the representation of objects of reality.

The technical drawing also allows us the representation of elements from different points of view, its front, a top view, the left side, the right and the bottom and the back.

Also, technical drawing can be done with the help of the computing. For this reason, there are certain programs (software) that facilitate projections and calculations to arrive at the most accurate drawing according to these.
At present, technical drawing has brought programs to the various fields of use, a fact that of course implies an enormous technical and design advance.

Meanwhile, the most commonly used manual instruments for this technique are rulers, compasses and squares.

Special use in architecture, urban planning and engineering

It also supports sketches, diagrams, diagrams, plans and other representations and the use of concepts. geometric figures and notions of mathematics to successfully achieve scales and perspectives when necessary.

The Architectureis the discipline that par excellence appeals to technical drawings. A building, for example, can be represented thanks to the technical drawing, in plan, with the top or ceiling view; or elevation, with its front and side view; Likewise, annotations and clarifications about its dimensions can be dumped in the plans, specifically, this type is called architectural drawing.
Urban planning and engineering are also other areas that make use of this type of drawing.

In the strict case of urban planning, it is thanks to the technical drawing that the various aspects that make up the public space, roads, basic services, among others, can be designed.
Each city has its own contingencies, features and demands and the urban planner must assess all these issues and of course through technical drawing translate it into sketches or projects that value and satisfy them as corresponds.

But there are also other types ...

The Mechanical drawing that deals with representing parts or parts of a machine, the electronic drawing, performs the representation of circuits, the electrical drawingOn the other hand, it outlines the electrical installations of an architectural structure; the geological, they use it geography and geology to represent the different layers of the earth and make known the minerals contained in each of the layers. And the urban drawing, which is used to organize the development of urban centers.
