CAD, or computer-aided design and drafting (CADD), is technology designed for creators to design, draft and produce technical documentation – replacing manual hand-drawn and drafting techniques with a digital-first process. Whether you’re an architect, designer, or engineer, you’ve probably used 2D or 3D CAD programs such as AutoCAD, AutoCAD LT, Civil 3D, Inventor, or Fusion 360 software. These widely used tools can help you explore design concepts, visualise with photorealistic renders and simulate real-world performance.
Choosing the right CAD software is pivotal for design efficiency. To decide effectively, first define your specific needs and goals, then match software features to your project requirements. Next, check compatibility (US site) with your preferred file formats and other software in the design workflow. Lastly, consider available learning resources (US site) such as tutorials, training and a supportive user community.

Cloud-based CAD software operates over the internet, storing design data remotely and enabling access from various devices. This approach enhances collaboration by allowing real-time, multi-user work on projects, while robust version control helps ensure design integrity. Users benefit from easy access to projects anywhere, reduced file-management complexity, automatic backups and heightened security measures.
CAD software is used by a diverse range of professions that require design precision and visualisation. Architects and landscape architects; engineers (across disciplines such as mechanical, civil, automotive, aerospace and electrical); designers (including product, industrial, graphic, mechanical, interior and jewellery); urban planners; and professionals in construction and surveying all rely on CAD. This software aids in creating detailed 2D and 3D models, schematics, layouts and plans, empowering professionals to conceptualise, design and optimise structures, products and systems efficiently across industries.
CAD software is available in various types to serve diverse design needs. Technical drawings use 2D CAD, whereas 3D CAD creates three-dimensional models for product design and architecture. Parametric CAD establishes relationships between elements, while direct modelling offers flexible design modifications. Surface modelling crafts curved surfaces and solid modelling defines volumes and mass. Rendering and animation software visualises designs realistically. Building information modelling (BIM) (US site) focuses on architecture and construction and electronic design automation (EDA) handles electronic systems. CAM generates manufacturing instructions and specialised CAD types exist for plant design, fashion design and more.
CAD software is a fundamental component of the 3D printing process. It enables the creation of intricate 3D models, optimises them for printing and generates compatible file formats such as STL. CAD tools facilitate the addition of support structures and help ensure model accuracy and scaling. By interfacing with slicing software, CAD helps divide models into printable layers and prepares them for 3D printing. The software also aids in prototyping, refining designs and preventing errors before the final print. In essence, CAD software’s role in 3D printing spans from initial design to creating printer-ready files.
There are numerous free CAD software options available, catering to a range of design needs. Autodesk’s offerings include Fusion 360 for 3D design and Tinkercad for simpler projects. FreeCAD is an open-source parametric modeller; Blender serves both 3D modelling and animation needs; and LibreCAD is specialised for 2D technical drawings. OpenSCAD adopts a scripting approach to design, while OnShape's free plan is cloud-based. SolveSpace focuses on parametric 3D mechanical design, and DraftSight offers 2D drafting capabilities. Additionally, ScorchCAD provides a user-friendly browser-based option. These free tools empower learners, hobbyists and other individuals to engage in design projects without financial constraints.
