CAD (Computer-Aided Design) is computer software popularly used for creating detailed 2D drawings or 3D models. CAD software is predominantly used by engineers, artists, drafters and architects for use in various design mediums.
CAD software helps designers to effectively visualise what their design will look like as a physical product. It helps to accurately plan out designs before moving towards the manufacturing process.
CAD software also allows us to realise any design flaws before a product is physically created. By creating a realistic visualisation of a design, it is possible to note any flaws in a design before moving forward to the production phase. This helps to save time, money, materials and helps to create an overall more refined product.
