In all its forms, drawing is a form of communication that person took throughout history to first represent the reality that surrounded them , but then it became more complex until they set up visual languages that, despite not representing anything specifically, they look for a graphic correlation with oral communication, and finally they are composed of graphics and conventions that began as drawings.
From its origin, graphic representation came to be considered the universal language , often serving so that person who did not understand the most widespread forms of communication of a person could interpret their traditions, customs and issues anyway.
It is no coincidence that cave paintings are permanent analysis material by anthropologists and researchers of ancient history from it is commonly the only means to understand the cultural elements of past eras.
Artistic and technical drawing
Quickly the drawing was divided into two broad categories : the entire part of the drawing aimed at seeking a representation as real as possible of the objects and the world was called technical drawing, while the part of the drawing that aspired to artistic expression of the author, without greater requirements than that, was called artistic drawing. It is clear that the two emerged as a necessity and were very valuable for the human being, but they were very different from each other.
To the extent that artistic drawing aims to express feelings, landscapes imagined forms or historical moments, this has a lot to do with the eye of the artist and his passions and moods at the time of reproduction.
It makes sense then that about the artistic drawing can be exhibitions, debates, awards, and that there are renowned artists of all ages, also many others of less prestige.
As for the technical drawing, the opposite occurs: there is no capacity for any expression, but what is sought is to accurately represent an object, with a completely practical and determined purpose, which must comply with a series of standards international in order to be understood, without giving rise to different interpretations, and valid anywhere in the world.
It is a normalized activity, which must be exercised with professionalism and with a deep preeminence of order and prolixity: nothing valuable can appear as a result of chance or chance (which could happen in any artistic discipline).
Features of the technical drawing
The technical drawing uses a series of very specific materials :
- Rule T
- Drawing board
The education in technical drawing is more or less widely depending on the production demands of each region, but in all cases commonly occur in two places: in secondary schools and technical guidance in schools of Design, Architecture or Engineering.
The areas in which the technical drawing circulates are those that give rise to the most frequent classification, which distinguishes between:
The technical drawing seeks to respond to the issue of design and construction, that is, it seeks to dimension in the most real way possible as it will be something that man imagines being able to build. It is the perfect bridge between the idea and the implementation because it is the exact plan with all the components and materials that will then allow to manufacture what has been arranged.
There is a full connection with physics: what the technical drawing represents will have the objective of being brought to reality, so you must be completely attentive to all contingencies and eventualities of physical order that point to the preservation and safety of the object. Precisely that is what takes so many years to oil and perfect, for those who are fully dedicated to the study of engineering.
The scope of technical drawing, today
The entire environment where person live is mediated by the product of engineering and architecture, which in all cases has gone through a process of graphic representation before its implementation.
This is the act by which the ideas that person had were expressed in order to then be put into practice. In this way, it seems logical that within the framework of graphic design geometric figures appear as recurringly as straight lines, curves, circumferences, and polygons.
Every engineer and architect must know how to make and interpret this kind of drawings, taking into account dimensions, proportions, and characteristics of the materials. It is assumed that the technical drawing is a source of information, therefore it must be complete and represent as completely as possible the entire object.
At present, the use of computer science, with various programs specially developed to support design and projection tasks, allow us to have a new dimension of technical drawing, based on the virtual recreations that can be achieved from objects in three dimensions, which completely revolutionized the work of architects and designers.
