How CAD changes the product design
From the fork to the food processor, from the bicycle to the car: in product design – also known as industrial design – creativity and technology merge. The more complex a product is, the more special are the abilities of the designers working on it. Because more and more work on design becomes a team task. In this article, we show you how Computer Aided Design (CAD) changes product design and what that means for people in this job.
3D modeling instead of drawing board
The activity of Industrial Designers has changed; As part of the digital transformation,complex software solutions not only replace the e ngineers’ pencil and drawing board, but also permit virtual visual and stress tests and make their own design proposals. This is how products come to life before they exist as real objects. These possibilities affect the industrial design and change the creative process permanently.
Industrial Design – More than beautiful appearance
More common than the term industrial design is commonly referred to as product design. However, this term is somewhat unclear. After all, product designers do not develop unique items, but rather products that are to be mass-produced industrially. This is more clearly expressed in the term industrial design.
Before an article goes into production, it goes through an intense process of creation . Industrial designers create the ideas, engineers or technicians determine the tolerances and dimensions and make drawings that are used to make a model using 3D modeling. This is subjected to functional and load tests and further modified as needed. Industrial design includes the development of consumer goods and capital goods such as machinery and equipment.
Whether consumer goods or technical equipment – they should work and look good. That is obvious to us right away. A third criterion, the symbolic character, is not always recognizable at first glance. But for most of us, it does not matter if we use a product that is futuristic or retro, it reflects our taste and, thus, a side of our personality. If we think of clothes, furniture or our car, this is easy to understand.
Industrial Design combines three criteria of a product:
These three criteria are weighted according to the product type. A machine has to work first and foremost; an espresso machine should be as functional as it is aesthetic and embody a certain style.
Industrial design used to be a long, often years-long process – from the idea, through concept creation, to the design, prototyping, and the necessary tests and corrections.
Thanks to modern software solutions such as 3D modeling on the computer, the design process today requires only a fraction of the time previously available and achieves much more precise solutions.
CAD – Rapid acceleration
CAD stands as an abbreviation for the English term “computer-aided design”; in German “computer-aided design”. This includes various steps:
- Create and vary a geometric model
- Perform all calculations
- Develop the product concept
- Simulate functions
- Gain information about the nature and functionality
CAD applications were originally used in industrial design to produce manufacturing records for production. In the meantime, expert systems are available to the designers, who develop and propose their own solutions based on the information contained, oriented towards a previously defined goal. AutoCAD training center in Coimbatore provides the best training for 3d modelling.
These expert systems are able to perceive the designed objects not only two-dimensionally, but as a body, so three-dimensional. This is how 3D digital modeling becomes possible; the true to scale production of a model that contains the most important properties of the object to be developed. From 3D model modeling software that supports the creation of a model and surface design to 3D printing, it’s just a step in which the model takes the leap from virtual to material existence.
What we have sketched out here in a few words means a profound change for industrial design: tests of function and load can be simulated on the digital model, the resulting changes take significantly less time and communication with suppliers is simplified by the exchange of production data.

Conclusion: 3D modeling accelerates industrial design
Fortunately, digitization does not stop at product design and offers good opportunities for faster and more efficient work processes. Anyone who develops their skills and acquires knowledge in the required software solutions for 3D modeling can work in an exciting and promising work environment.
