Industrial design or technical drawing: what is it?

First of all, let's clarify what a technical drawing is.

It's about, To represent elements, products, buildings, industrial parts, plans in a precise way and from different perspectives.

A discipline that has little to do with newspaper caricature, for example!

While the drawings used to be made manually on a drafting table, nowadays the draftsman has put squares and compasses aside. He mainly works with computers that work with CAD (Computer Aided Design) and CADD (Computer Aided Design and Drafting) software.

Technical drawing covers several areas:

  • The formal and descriptive representation of a concept to make sure it matches the designer's vision.
  • The technical transmission of data the professions involved in the implementation of the project (plans, functional principle, overall concept ...).

Technical drawing or industrial design can be used in mechanical engineering, construction, electrical engineering, but also in electronics. It is essential for the responsible engineering teams to develop a prototype.

The industrial design takes into account all elements of the requirements communicated to the draftsman. The information transmitted in this way relates to the dimensions of the elements, their shape or the materials used. By creating sketches and diagrams, the draftsman also contributes to checking the reliability of the project, the risk analysis, but also the production costs.

Whether it is the creation of an industrial product or the implementation of an architectural project, the technical drawing is the first step in implementing the concept. It is used in various areas of activity:

  • Automotive industry,
  • Aviation,
  • Mechanical engineering,
  • Interior design,
  • High-tech,
  • Construction drawing ...

The technical draftsman is at the center of the product development process. His drawings make it possible to establish the connection between the designer and the producer. He has to work in a team with the engineers responsible for the project.

History and development of industrial design

To know where the technical drawing came from, you have to go back to the 15th century!

Especially the great artist Leonardo there Vincibegan to combine scientific interest and artistic skills: the visual arts became a platform for science and innovation.

But only in the Renaissance the three-dimensional perspective appeared. The artists of the time noticed that the objects appeared smaller and smaller as the distance from the viewer increased. The Dutch painter Jan Van Eyck began to use the reflection of light to create increasingly realistic drawings.

In the time of the industrial revolution, progress in the field of technical drawing accelerated!

Industrial and agricultural inventions multiplied at a rapid pace, which is why it became necessary a lot more precise and complex drawings of machines to develop. For the first time the term "industrial design", which is used in most mechanical engineering branches, is mentioned.

Over the years, drawing on paper has given way to drawing with sophisticated software such as LibreCad, CAD or Micôsystème. The main interest of this type of Freeware is to allow the designer to rotate his models around any axis with just his mouse!

The different types of industrial designs

The job of the industrial draftsman is to create different types of drawings.

They can be divided into broad categories:

  • The sketch: This is the first draft of a project. Usually the sketch is made by hand and is not yet polished. Nevertheless, it gives a first overall impression of the concept. This is useful during the design phase. The sketch is also available in other disciplines, such as realistic drawing. But never in classic and satirical cartoons.
  • The layout: This is a standardized drawing made up of symbols. These make it possible to quickly display the functions and properties of a product in a simplified manner.
  • The overview drawing: It is a true-to-scale drawing that shows the entire project in a non-schematic form. It is used in the conception phase and highlights the chosen solutions.
  • The assembly drawing: This represents the product in its entirety. All components and their functions are listed there. S is a useful document when the designer submits a project to a manufacturer.
  • The manufacturing drawing: Based on the assembly drawings, the manufacturing drawing provides useful information for the manufacture of the elements that make up the end product.
  • The detail drawing: These are enlargements of part of the project. By specifying a certain element of the whole, the draftsman can use these details to clarify a certain point. In the production process, the detail drawing often supplements the production drawing.

What are the standards of industrial design?

Industrial design meets specific standards. It must be clear and easy to understand for everyone. The technical draftsman therefore adheres to standardized norms. In France, AFNOR sets the standards for the preparation of technical drawings.

It is a profession where accuracy in design is essential. There are several important points among industrial design standards.

Standards and formats

Depending on the subject of the technical drawing, it is not always possible to show it in its original size. Scales are used to reduce or enlarge the model and to represent it on a sheet of paper.

The formats are also standardized. There are 5 formats:

  1. A 4 210 × 297 mm
  2. A 3 420 × 297 mm
  3. A 2 420 × 594 mm
  4. A 1 840 x 594 mm
  5. A 0 840 x 1188 mm

Even the paper folding leaves nothing to chance. The sheets must always be folded so that they fit in an A4 pocket.

When folding, the text field is always aligned so that it is visible without having to unfold the sheet.

This makes it easier to archive documents.

The title block

It is a frame that contains a certain amount of mandatory information about the drawing. The information it contains includes:

  • The name of the drawing,
  • the scale used,
  • the name of the draftsman and the company,
  • the projection method (European or American),
  • the date,
  • the format of the drawing.

The dimensions of the text field are just as clearly defined as its position on the sheet. Traditionally, it's in the lower right corner of the drawing. The position can also vary depending on the type of drawing. The aim of the title block is to be able to identify the content of the drawing without having to open it.

The lines of the technical drawings also correspond to the specific standards the NF E 04-520 ISO 128. So there is:

  • Thick lines,
  • fine lines,
  • very fine lines,
  • dashed lines,
  • solid lines,
  • Dash-dotted lines.

This variety of lines enables the draftsman to give specific information about the elements shown. Dashed lines represent e.g. B. Hidden elements and fine lines are used for dimensioning.

The views

How can you draw an object completely?

The focus of the draftsman's work is on the views. The draftsman can use it to represent the object thanks to different views and enables a complete representation of the object. Practice in an acrylic painting class.

The drawing can thus show 6 different views: Front and rear view, as well as side view left, right, top view and bottom view.

Their arrangement is also precisely defined. There are two projection methods: American and European.

The European representation, in which the views are positioned taking into account the projection system. Specifically, one assumes that when one stands on the right side of an object, the view one has of it is projected to the left. Therefore, the right view is shown on the left side of the drawing. So on a technical drawing you can find:

  • The top view shown below the front view,
  • the left view to the right of the front view,
  • the bottom view shown above the front view,
  • The rear view on the far right in the drawing, next to the side view on the left ...

Draftsmen who are in the drawing process must also create 3D representations, cavalier perspectives, and section planes as required.

What material do you need to learn industrial design?

Do you want to create a 2D drawing, 3D object, or 3D modeling, but you don't know where to start? Superprof explains how to get your first professional drawing material!

Remember that there are two ways to create an engineering drawing: on paper or on digital media. In order to create a digital model or implementation plans on paper, you must therefore be equipped with another drawing material.

For the technical drawing on paper, the draftsman must acquire:

  • Measuring tools, plotting tools, geometry tools and cutting tools,
  • an adjustable drawing table,
  • Markers or pencils with a calibrated tip,
  • high quality drawing paper,
  • a rolling ruler,
  • a cutting ruler,
  • a drawing board,
  • a paper clip, etc.

You should know that there are many Beginner sets for draftsmen, which is very practical as it gives you all the materials you need to create your first technical drawing!

Digital drawing is a slightly different task. First, make sure to buy a good quality computer with good memory so that you can work quickly and efficiently. It is also possible to have some digital tablets such as those from the Apple brand, which are ideal for home drawing.

The draftsman then has to decide whether he wants a free software for industrial design installed or used a paid version. The free versions are logically much less sophisticated than their counterparts. Some paid software products, such as the CAD software, are used as a reference for modeling and developing a 3D drawing.

With the right IT tools, you can be sure that you can do your job as a draftsman!
