AutoCAD is a CAD software application for 2D and 3D design and drafting. It is developed and sold by Autodesk, Inc. First released in December 1982, AutoCAD was one of the first CAD programs to run on personal computers, notably the IBM PC. At that time, most other CAD programs ran on mainframe computers or mini-computers which were connected to a graphics computer terminal for each user.

AutoCAD Essentials is a multi-part series that takes a more modular approach to this massive program, used for everything from 2D and 3D CAD design, drafting, and modeling to architectural drawing and engineering projects. In this installment, author Jeff Bartels concentrates on the particulars of creating basic geometry in AutoCAD, including assigning imperial or metric units of measurement, using object snaps to control accuracy, and drawing and transforming basic lines and shapes. The last chapter in the course tests your newfound skills in a short project.

References in AutoCAD allow designs to be seen as more than just single drawings. In addition to standard line work, AutoCAD drawings can support images and store project data. Designers can also create projects that link drawings together, each one representing a component of the overall design. In AutoCAD 2009: Mastering References, Jeff Bartels goes deeper into the application, using his experience with civil engineering construction drawings to explore the concept of referencing. Using practical examples, Jeff teaches how to maintain project data, automate parts lists, make global changes using external references, incorporate imagery into drawings, and more. Exercise files accompany the course.
