CAD, in its full form computer-aided design, corresponds to the utilisation of computer software technology to assist in the creation, design and optimisation of objects.
The software is mostly used by architects and engineers to develop their ideas both in 2D and 3D.
With the growth of 3D printing technology, CAD systems are becoming more user-friendly and reaching out to the masses helping people less design-savvy model and build their 3D objects.
