INTRODUCTION TO AUTOCAD AutoCAD is a commercial computer-aided design (CAD) and drafting software application. Developed and marketed by Autodesk, AutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers. Prior to the introduction of AutoCAD, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal. Since 2010, AutoCAD was released as a mobile- and web app as well, marketed as AutoCAD 360. AutoCAD is used across a wide range of industries, by architects, project managers, engineers, graphic designers, and many other professionals. It was supported by 750 training centers worldwide in 1994. Vertical integration Autodesk has also developed a few vertical programs: • AutoCAD Architecture • AutoCAD Civil • AutoCAD Electrical • AutoCAD ecscad • AutoCAD Map 3D • AutoCAD Mechanical • AutoCAD MEPs • AutoCAD Structural Detailing • AutoCAD Utility Design • AutoCAD P& ID • AutoCAD Plant 3D AutoCAD LT • 3D Capabilities: AutoCAD LT lacks the ability to create, visualize and render 3D models as well as 3D printing. • Network Licensing: AutoCAD LT cannot be used on multiple machines over a network. • Customization: AutoCAD LT does not support customization with LISP, ARX, .NET and VBA. • Management and automation capabilities with Sheet Set Manager and Action Recorder. • CAD standards management tools.
