What is technical drawing?

Do you have a more Cartesian spirit?

A scientist’s soul?

Technical drawing, also called industrial drawing , is the opposite of creative drawing. This discipline, essential in engineering, consists of representing products, prototypes and projects of all kinds through drawings. it is a system or language to represent objects within the context of industrial and design activities, following a series of rules.

Assembly plans and modelers.
Technical drawing is an area in which precision and rigor are essential.

It is especially important because it is a means of communication and transmission of essential information  when developing and developing new concepts and products.


  • The assembly plans for a new piece of furniture,
  • architectural projects,
  • industrial products (automobile, aeronautics …),
  • electronics and its schemes,

The key word in technical drawing? Precision , since the technical drawing accurately and concisely describes the dimensions, shapes, characteristics and construction of an object to be reproduced.

Before launching into the production of a specific piece, you have to have a concrete representation from all angles. That’s where the modeler comes in . His drawings, from different angles, cutting plans, dimensions … present the product in an exhaustive way, since it regroups all the useful information.

Industrial drawing respects the numerous regulations in force that they dictate, for example:

  • The format of the drawings,
  • the strokes used,
  • the elements to mention in the drawing,
  • the layout of the views,

What can distinguish technical drawing from any other type of drawing? Mainly, the difference is that artistic drawing is usually much more subjective and is open to interpretation, according to which one person can see something completely different from another. However, this does not happen in technical drawing as it is totally clear that what is shown or represented is as is and there is no room for interpretation.

In fact, thanks to the rules of technical drawing, those interpretations that can even give rise to confusion are avoided.

Who can turn to technical drawing? In addition to engineers and architects, many professionals can use technical drawing. For example, teachers, interior or product designers, bricklayers, plumbers or electricians, among others.

We have the image of the modeler in front of his drawing table, working with his compass and his square. However, today this trade has changed a lot and industrial drawing professionals work with computers thanks to design programs. It is a job in which rigor is essential, but it allows working in very diverse sectors of activities.
