AutoCAD is computer-aided design (CAD) software by Autodesk used to create precise 2D and 3D drawings and models for industries like engineering, architecture, and construction. It offers tools for drafting, modeling solids and surfaces, and includes industry-specific toolsets, improving productivity through automation, precise designs, and cloud access. Users can create, edit, and annotate digital designs more quickly and accurately than with manual methods, with features to manage layers, reuse components, and collaborate across desktop, web, and mobile devices.
