This document provides an overview of AutoCAD, including: - AutoCAD is 2D and 3D computer-aided drafting software useful for mechanical, civil, and architectural design. It allows users to create blueprints, floor plans, 3D models, and construction drawings. - AutoCAD was developed in 1982 by Autodesk to aid programmers in all aspects of 2D and 3D design, building upon earlier CAD software from the 1950s-60s. - Key concepts in AutoCAD include layers for organizing drawings, coordinate systems, drawing commands, and modifying commands for moving, rotating, copying objects. The interface provides tools for commands, views, and a drawing space to work in.
