AutoCAD is a computer-aided design software built for engineers and architects to create accurate 3D and 2D drawings. It automates various tasks such as creating schedules, adding blocks, comparing models, and more.

The software is equipped with numerous industry-specific programs for mechanical engineering, architecture, and electrical design.

The mechanical toolset, for example, adds a library of standards-based components to help users build, modify and document mechanical designs for manufacturing. It includes more than 700,000 intelligent manufacturing parts and functions to support ANSI, JIS, DIN, CSN, GB, and ISO standards.

AutoCAD supports many APIs and plugins for customization and automation. Its drawing exchange format, DXF, allows importing and exporting model data.
