AutoCAD is a computer-aided design software developed by the company Autodesk (hence the name AutoCAD). It allows you to draw and edit digital 2D and 3D designs more quickly and easily than you could by hand. The files can also be easily saved and stored in the cloud, so they be accessed anywhere at anytime.
AutoCAD designers use computer software to create technical drawings based on the work of architects and engineers. Some designers specialize in particular types of drawing, such as architectural or mechanical.
