The basics of CAD

CAD, or computer aided design, relates to anything that’s been created using a computer. And because computers are widely used across almost all industries, there are a wealth of 2D and 3D objects and systems that have CAD to thank for their creation. 

We’ll take a detailed look at which industries commonly use computer aided design, what the benefits of CAD are and some popular CAD software. 

Who uses CAD? 

Anyone can use computer aided design as long as they have the right CAD software but you’ll typically find it being used extensively in the following industries: 

  • Architecture: CAD has transformed architecture, allowing designers to create accurate plans that adhere to strict safety standards and that meet the needs of the users.
  • Automotive: Vehicle design has been streamlined with the use of CAD, with every component designed by special software.
  • Aeronautics: CAD software is used in this industry to design and test 3D models to aid in the manufacturing of air and space craft. The UK is home to the second largest aerospace industry in the world with a wealth of companies that rely on such software in the supply chain. 
  • Engineering: Many fields of engineering rely on computer aided design for a variety of projects.
  • Manufacturing: Designs are commonly created and tested using CAD before finalising the end product.

There are also many other industries that utilise computer aided design such as interior design, dentistry and fashion. 

What are the benefits of using CAD?

There are a variety of reasons why different industries choose to use computer aided design, but the main ones include: 

  • The ability to create more accurate designs with increased detail, showing a truer representation of the final model or product. 
  • Reduction of human errors. 
  • Increased productivity and efficiency due to the reduction in time to create a 2D or 3D model. 
  • Increased safety standards, particularly when creating engineering, aircraft and architectural designs. 
  • A streamlined testing process with opportunities to optimise and enhance models before the final production stage. 

What are some examples of CAD software? 

There are many different types of CAD software on the market, suited to both professionals and those wanting to create computer aided designs as part of their hobby, such as game designers. Some examples include Brics CAD, AutoCAD, SolidWorks, Revit and Inventor. 

As the use of such software increases, many companies are starting to look for computer aided design skills from their employers as well experience in using some of the popular programmes. 

There’s no doubt that CAD will play a huge role in the design and creation of even more products, systems and applications in the future. And, as technology and software capabilities increase, such as with the advancement of AI in smart factories, the way products and systems are designed and manufactured will continue to change and become even more efficient.
