AutoCAD is a complete design tool, with the basic features of the professional industry standard architecture. After its release, Autodesk continuously improved AutoCAD by adding features such as mechanical, electrical, thermal, lighting, cable and so on. AutoCAD is the first CAD program that created a fully parametric 3D model, which is more user-friendly. 3D editing tools make AutoCAD a preferable choice for architects, engineers, contractors and designers, both for professional and hobbyist applications. The design document can be saved as DWG, DXF, PDF or HTML files, which enables users to easily edit or view the document in any CAD software, as well as print the drawing for use in the field.

Main Features of AutoCAD


AutoCAD provides support for the American National Standards Institute (ANSI) standard file format, the Digital Exchange Format (DXF) which is widely used by CAD software programs in the industry. This format was chosen for compatibility reasons. It is ANSI-standardized and has the ability to contain information and data about every single drawing element. DXF files can be opened, edited and saved in AutoCAD.


AutoCAD also supports the Portable Document Format (PDF) format, as well as HTML, with support for hypertext markup language. The files can be opened, edited and saved in AutoCAD.

Support for both DWG and DXF files enables users to work with drawings or drawings exchanged with other applications.

Masters of AutoCAD

AutoCAD provides the capability of creating masters of your AutoCAD documents that can be used to quickly reload AutoCAD documents. The workflow using masters involves creation of new drawing, the creation of the master document, the reloading of the drawing into the new master, the editing of the drawing in the master, and then resaving the master as a file.

AutoCAD Filenames

AutoCAD supports file name case sensitivity. In other words, you cannot create a file named “Excel” and attach it to an AutoCAD drawing. The AutoCAD file name is case-sensitive. This is a feature that you will find missing in some other CAD programs.


Import and export files to and from other applications. AutoCAD provides full support for exchange of files between its own native

Structured Web Services (SWS) is a feature in AutoCAD which provides XML-based APIs for developing and accessing applications through web services, including SWS.

BIDS (Bidirectional Interface Development System) is a Visual Studio project type that helps create non-visual applications using Autodesk products.

Bits and pieces
AutoCAD is a graphic-intensive software, and therefore it consumes more computer resources than other similarly structured applications. As a result, the average computer user will spend more time waiting for AutoCAD to load. Therefore, it is common practice to keep the AutoCAD program and other programs loaded in memory at the same time to avoid performance degradation. It is also useful to allow certain programs to “run in the background”, such as email and chat programs. A computer with multiple drives is a benefit when drawing with AutoCAD, since it allows the user to work on several drawings at once.

Some common computer applications that may interact with AutoCAD:
Microsoft Windows: Word, Excel, PowerPoint, Excel Services, Outlook, Access, WordPad, Notepad++, Paint, Photo viewer, IM client, games, various others
Google Chrome, Mozilla Firefox, Internet Explorer, Apple Safari, Apple Mail, Acrobat Reader
Autodesk products: AutoCAD, AutoCAD LT, Autodesk MotionBuilder, Plant 3D
Adobe products: Photoshop, Illustrator, InDesign, InCopy
Unigraphics NX
AutoCAD LT and AutoCAD LT Mobile may be accessed from other applications via the AutoCAD System Manager.


AutoCAD LT (AutoCAD for the LT (light-table) is a software application by Autodesk for architectural, engineering, and construction information and collaboration. Its basic purpose is the editing of design drawings. However, it is also usable for drafting of technical and architectural plans, and is specifically designed for office use. Its primary purpose is to provide the CAD operator with a set of powerful features, including revision, BIM interoperability, import/export support, advanced 2D drafting, and 2D/3D data management. AutoCAD LT is a discontinued product and it was discontinued on March 20, 2017.

AutoCAD LT Mobile

AutoCAD LT Mobile (for Android devices) is the CAD/BIM application counterpart to AutoCAD LT. Originally the AutoCAD LT Mobile application was
