AutoCAD^® is computer-aided design (CAD) software that architects, engineers, and construction professionals rely on to create precise 2D and 3D drawings.

• Draft, annotate, and design 2D geometry and 3D models with solids, surfaces, and mesh objects
• Automate tasks such as comparing drawings, adding blocks, creating schedules, and more
• Customize with add-on apps and APIs
