Engineers and designers use computer-aided design (CAD) software to create, analyze, model, and modify 2D and 3D designs that may be used in a range of systems and products, such as structures, electrical circuits, mechanical parts, and more.
Although these tools are built specifically for professionals for purposes such as visualization, simulation, 3D printing, and many more, they can also be used for a number of basic 2D and 3D functions, including editing and viewing models.
On the other hand, while most CAD programs are always subscription-based, some of them still offer a free option or are completely free.
This is useful for individuals who only need to practice 2D/3D modeling or who only need to undertake basic CAD design and don’t want to commit any money, hence needing only a limited set of features.
