Technical drawing is a representation system.
A drawing is a figure , image or delineation that is usually made manually with the help of a tool (a pencil, a brush) on different materials. The concept of technical , on the other hand, refers to a procedure linked to science whose objective is to obtain a certain result.
The system of graphic representation of different types of objects is known as technical drawing . Its purpose is to provide the information necessary to analyze the object, help its design and enable its construction or maintenance.
The help of technology
Technical drawing can be developed with the help of computing . There are certain programs ( software ) that allow projections and calculations to be made that facilitate drawing. As for manual instruments, the most common are rules, squares and compasses.
Architecture , for example, is a science that uses technical drawings. A building can be represented in plan (with a top view, roof view, etc.) or elevation (front view, side view), with clarifications about its dimensions on the plans. In this case, we speak of architectural drawing.
In this sense, it must also be clarified that the plan is the representation of the object that is made on what would be a horizontal period. And also in technical drawing it is usually decided to present this, or the elevation, together with a series of fundamental indications to be able to understand it in the most exact way possible.
This means that any drawing of this typology is accompanied, in addition to the already mentioned dimensions, by the corresponding dimensions. These can be size, position or location, fundamentally.
In architecture, technical drawing is usually used.
Types of technical drawing
Among the many types of technical drawing we could highlight, for example, the geological drawing that, as its name indicates, is used in the field of Geology and Geography for issues such as working in mining deposits or representing the different layers of the Earth. .
Other types of technical drawings are the mechanical drawing (representing pieces or parts of machines), the electronic drawing (the representation of circuits), the electrical drawing (the delineation of the electrical installations of an architectural structure) and the urban planning drawing (used to organize the development of urban centers).
Technical drawing may include sketches , diagrams , diagrams, plans, and other types of representations. Geometric concepts and mathematical notions are often used to work successfully with scales and perspectives.
a subject
In the same way, we must not forget that Technical Drawing is a subject that is taught at different levels within the Spanish educational system. It is intended that students not only learn certain theoretical concepts, such as vocabulary, related to said discipline but also a series of skills and manual skills to undertake the creation of this type of drawings.
Specifically, in the 1st and 2nd year of Baccalaureate courses, this subject is taught and for its development, as well as for student learning, there are interactive resources such as various web applications that the Ministry incorporates on its Internet page. of Education and Science.
