Design in a digital age

What is Computer-Aided Design (CAD)

3D CAD, or three-dimensional computer-aided design, is a widely used technology by engineers, product designers, and drafters to create functional virtual prototypes of 3D objects. Through 3D CAD, they have the ability to design and dynamically modify products, parts, or assemblies with an extremely high level of detail. 3D CAD software also simplifies and automates other aspects of product engineering, such as test simulations, manufacturing, data management, and even computer animation.
These three-dimensional models can be used in simulation studies to predict the behavior of an object under constraints or environmental factors. Additionally, they can also be used to create photorealistic images for commercial and marketing documentation purposes. Detailed drawings can be sent to the manufacturing department for use in the production process, and in the case of additive manufacturing, the CAD file can be directly transferred to a 3D printer.


CAD Software, an Integral Part of Digitalization

The increasing digitization and interconnectivity brought about by Industry 4.0 have presented new challenges for manufacturing companies. Growing customer demands and the need for customized product designs add additional pressure on developers and manufacturers.

In our view, in the digital era, computer-aided design (CAD) forms the foundation for mastering this complexity in a continuous development process. CAD serves as the basis for analytical calculations, driving the development process, and information cells for manufacturing processes. Never before in the history of CAD has software played such a predominant role, as a factor for success in today's volatile markets, and for ensuring the sustainability of design & manufacturing companies. Build your foundations and take advantage of the opportunities offered by CAD software.

The quality and complexity dimensions are also of prime importance, as CAD software must be capable of adapting to a wide range of industrial sectors. One can imagine, for example, the complexity of CAD processes in the defence and aeronautics industries, or the meticulousness and tight deadlines imposed during design cycles in the medical industry with implantable medical devices, for example... The tools available in the software, its ability to evolve over the long term, and the responsiveness of the support teams of your CAD/CAM service partner (like JANUS Engineering) are all factors not to be overlooked.

Advantages of CAD systems

  • Better visualisation options for the end product, sub-assemblies and other components speed up the design process
  • Reduce errors in the design process with targeted control mechanisms directly integrated into NX CAD software
  • Problem-free reuse of design data and best practices
  • Simplified, more comprehensive documentation of the design, including geometries and measurements, parts lists, etc.
  • Reduced product development costs, increased productivity and a faster market launch


How to choose the right CAD software ?

Choosing the right Computer-Aided Design (CAD) software is crucial for design and engineering professionals, as well as the subsequent manufacturing process. With a multitude of software options available in the market, it can be challenging to determine the one that best suits your needs. However, by considering certain essential criteria, you can make an informed decision. Here are five points to consider.

  1. The quality of user experience and ease of use :
    When selecting CAD software, the user interface and ease of use are paramount. The computer-aided design process should be smooth and intuitive, enabling users to efficiently create 3D models. Opt for software with a user-friendly interface, ergonomic features, and advanced automation capabilities such as artificial intelligence, machine learning, and voice commands. These features will facilitate your work and foster continuous innovation.

  2. The breadth of features and industry focus:
    It is important to choose CAD software that offers advanced tools tailored to your specific design needs, take a closer look at the different 3D CAD modeling principles offered by solutions on the market. Whether you work in architecture, mechanical engineering, or any other discipline, ensure that the software provides the necessary features for your field of work. Also, consider the size of your organization and collaboration needs, such as version management, revisions, or project-based work.

  3. Openness and flexibility of the software:
    Ensure that the chosen CAD software is compatible with other commonly used software and file formats in your industry, as well as your existing digital tools and software. This compatibility will facilitate seamless file exchange with colleagues, partners, and clients, without encountering compatibility issues. Also, consider your long-term ambitions and select software capable of adapting to future organizational and structural changes in your company.

  4. The availability of training resources and technical support:
    When selecting CAD software, the assistance and training provided by the provider are important considerations. Choose a provider that offers tutorials, online or on-site training, as well as responsive and competent technical support. This support will be invaluable when you require guidance to resolve issues or seek answers to specific questions during your CAD software usage.

  5. Operating costs:
    Don't forget to consider the operating costs associated with using CAD software. Maintenance fees, for instance, can vary significantly based on the offered features and purchasing or subscription options. Carefully evaluate your acquisition and operating budget, and compare the different available offerings in the market.


How to choose your CAD software, overview

In summary, it is crucial to conduct thorough research and take the time to select the ideal CAD software for your business. By keeping in mind criteria such as user-friendliness, advanced features, compatibility, flexibility, technical support, and costs, you will be able to make an informed decision. Remember that computer-aided design and engineering play a central role in your business, and investing in sustainable, proven, and high-quality CAD software will optimize your productivity and deliver exceptional results in your design projects. Make the right choice for yourself and your company, and harness the full potential of CAD to achieve innovative and high-quality creations.
