The student version of AutoCAD is functionally identical to the full commercial version, with one exception: DWG files created or edited by a student version have an internal bit-flag set (the "educational flag"). When such a DWG file is printed by any version of AutoCAD (commercial or student), the output will include a plot stamp / banner on all four sides. Objects created in the Student Version cannot be used for commercial use. These Student Version objects can and will 'infect' a commercial version DWG file if imported</p><p align="left"><strong><u><span style="font-size:130%;color:#ff0000;"><em>Vertical programs</em></span></u></strong></p><p align="left">Autodesk has also developed a few vertical programs, sometimes called Desktops, for discipline-specific enhancements. AutoCAD Architecture (formerly Architectural Desktop), for example, permits architectural designers to draw 3D objects such as walls, doors and windows, with more intelligent data associated with them, rather than simple objects such as lines and circles. The data can be programmed to represent specific architectural products sold in the construction industry, or extracted into a data file for pricing, materials estimation, and other values related to the objects represented. Additional tools allow designers to generate standard 2D drawings, such as elevations and sections, from a 3D architectural model. Similarly, Civil Design, Civil Design 3D, and Civil Design Professional allow data-specific objects to be used, allowing standard civil engineering calculations to be made and represented easily. <a class="new" title="AutoCAD Mechanical (page does not exist)" href="http://en.wikipedia.org/w/index.php?title=AutoCAD_Mechanical&action=edit&redlink=1">AutoCAD Mechanical</a>, <a title="AutoCAD Electrical" href="http://en.wikipedia.org/wiki/AutoCAD_Electrical">AutoCAD Electrical</a>, AutoCAD Civil 3D, and AutoCAD Map 3D are other examples of industry-specific CAD applications built on the AutoCAD platform.</p><p align="left"><strong>AutoCAD </strong>is a <a title="Computer-aided design" href="http://en.wikipedia.org/wiki/Computer-aided_design">CAD</a> <a class="mw-redirect" title="Software application" href="http://en.wikipedia.org/wiki/Software_application">software application</a> for <a class="mw-redirect" title="2d computer graphics" href="http://en.wikipedia.org/wiki/2d_computer_graphics">2D</a> and <a class="mw-redirect" title="3d computer graphics" href="http://en.wikipedia.org/wiki/3d_computer_graphics">3D</a> <a title="Design" href="http://en.wikipedia.org/wiki/Design">design</a> and <a title="Technical drawing" href="http://en.wikipedia.org/wiki/Technical_drawing">drafting</a>, developed and sold by <a title="Autodesk" href="http://en.wikipedia.org/wiki/Autodesk">Autodesk</a>, Inc.

Since the mid-1990s, AutoCAD has supported custom objects through its C++ API. Modern AutoCAD includes a full set of basic solid modeling and 3D tools, but lacks some of the more advanced capabilities of <a title="Solid modeling" href="http://en.wikipedia.org/wiki/Solid_modeling">solid modeling</a> applications</p><p align="left"><strong>AutoCAD</strong> supports a number of <a title="Application programming interface" href="http://en.wikipedia.org/wiki/Application_programming_interface">application programming interfaces</a> (APIs) for customization and automation.

ObjectARX is a <a title="C++" href="http://en.wikipedia.org/wiki/C%2B%2B">C++</a> class library, which was also the base for products extending AutoCAD functionality to specific fields, to create products such as AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D, or third-party AutoCAD-based applications.</p><p align="left"><strong>AutoCAD's</strong> native file format, <a title=".dwg" href="http://en.wikipedia.org/wiki/.dwg">DWG</a>, and to a lesser extent, its interchange file format, <a class="mw-redirect" title="DXF" href="http://en.wikipedia.org/wiki/DXF">DXF</a>, have become <a title="De facto" href="http://en.wikipedia.org/wiki/De_facto">de facto</a> standards for CAD data <a title="Interoperability" href="http://en.wikipedia.org/wiki/Interoperability">interoperability</a>.
