CAD (Computer-Aided Design)
Computer-Aided Design (CAD) refers to the use of specialised software tools for drafting, modelling, and visualising technical drawings and design concepts in two or three dimensions. It plays a central role in fields such as architecture, mechanical engineering, industrial design, and construction.
CAD systems, such as AutoCAD, Fusion 360 and SolidWorks, support both 2D drafting and complex 3D modelling. They enable designers and engineers to:
- Create accurate and detailed design plans
- Simulate structural and mechanical behaviour
- Perform parametric modelling and digital prototyping
- Collaborate across disciplines using shared file formats (e.g. DWG, STEP, IGES)
CAD enhances design precision, reduces human error, and shortens the iteration cycle by allowing visualisation and testing of components before physical production. Its integration with manufacturing systems (e.g. CAM and CNC) makes it a vital part of modern digital design workflows.
