AutoCAD is a 2D and 3D laptop-aided design (CAD) software program application for desktop, internet, and cell developed by Autodesk.[1] It was first released in December 1982 for the CP/M and IBM Pc platforms as a desktop app working on microcomputers with inside graphics controllers.[2] Initially a DOS software, subsequent versions were later launched for other platforms including Classic Mac OS (1992), Microsoft Windows (1992), web browsers (2010), iOS (2010), macOS (2010), and Android (2011).

AutoCAD is a general drafting and design software utilized in trade by architects, undertaking managers, engineers, graphic designers, city planners and other professionals to arrange technical drawings. After discontinuing the sale of perpetual licenses in January 2016,[3] industrial versions of AutoCAD are licensed by means of a time period-based subscription.

History[edit]

Before AutoCAD was launched, most business CAD packages ran on mainframe computer systems or minicomputers, with every CAD operator (user) working at a separate graphics terminal.[4]

Origins[edit]

AutoCAD was derived from a program that started in 1977, after which released in 1979[5] known as Interact CAD,[6][7][8] also referred to in early Autodesk paperwork as MicroCAD, which was written previous to Autodesk's (then Marinchip Software Partners) formation by Autodesk cofounder Michael Riddle.[9][10]

The primary version by Autodesk was demonstrated at the 1982 Comdex and released that December. AutoCAD supported CP/M-eighty computer systems.[11] As Autodesk's flagship product, by March 1986 AutoCAD had become probably the most ubiquitous CAD program worldwide.[12] The 2022 release marked the 36th major launch of AutoCAD for Windows and the 12th consecutive yr of AutoCAD for Mac. The native file format of AutoCAD is .dwg. This and, to a lesser extent, its interchange file format DXF, have turn into de facto, if proprietary, standards for CAD knowledge interoperability, notably for 2D drawing trade.[13] AutoCAD has included support for .dwf, a format developed and promoted by Autodesk, for publishing CAD information.

Features[edit]

Compatibility with other software[edit]

ESRI ArcMap 10 permits export as AutoCAD drawing information. Civil 3D permits export as AutoCAD objects and as LandXML. Third-get together file converters exist for particular codecs such as Bentley MX GENIO Extension, PISTE Extension (France), ISYBAU (Germany), OKSTRA and Microdrainage (UK);[14] also, conversion of .pdf files is feasible, nevertheless, the accuracy of the results could also be unpredictable or distorted. For example, jagged edges might appear. Several vendors provide on-line conversions totally free resembling Cometdocs.

Language[edit]

AutoCAD and AutoCAD LT can be found for English, German, French, Italian, Spanish, Japanese, Korean, Chinese Simplified, Chinese Traditional, Brazilian Portuguese, Russian, Czech, Polish and Hungarian (additionally via additional language packs).[15] The extent of localization varies from full translation of the product to documentation solely. The AutoCAD command set is localized as a part of the software program localization.

Extensions[edit]

AutoCAD helps a number of APIs for customization and automation. These embody AutoLISP, Visual LISP, VBA, .Net and ObjectARX. ObjectARX is a C++ class library, which was additionally the base for:

- merchandise extending AutoCAD functionality to specific fields- creating merchandise akin to AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D- third-get together AutoCAD-primarily based application
There are a large number of AutoCAD plugins (add-on functions) accessible on the appliance store Autodesk Exchange Apps.[16] AutoCAD's DXF, drawing trade format, allows importing and exporting drawing information.

Vertical integration[edit]

Autodesk has additionally developed a number of vertical packages for discipline-specific enhancements comparable to:

Advance SteelAutoCAD Architecture- AutoCAD Electrical- AutoCAD Map 3D- AutoCAD Mechanical- AutoCAD MEP- AutoCAD Plant 3D- Autodesk Civil 3D
Since AutoCAD 2019 a number of verticals are included with AutoCAD subscription as Industry-Specific Toolset.

For example, AutoCAD Architecture (formerly Architectural Desktop) permits architectural designers to attract 3D objects, equivalent to walls, doors, and home windows, with extra clever information associated with them fairly than simple objects, resembling strains and circles. The info might be programmed to characterize specific architectural products sold in the development industry, or extracted into a knowledge file for pricing, supplies estimation, and different values related to the objects represented.

Additional instruments generate commonplace 2D drawings, corresponding to elevations and sections, from a 3D architectural model. Similarly, Civil Design, Civil Design 3D, and Civil Design Professional assist information-specific objects facilitating simple commonplace civil engineering calculations and representations.

Softdesk Civil was developed as an AutoCAD add-on by a company in New Hampshire called Softdesk (originally DCA). Softdesk was acquired by Autodesk, and Civil grew to become Land Development Desktop (LDD), later renamed Land Desktop. Civil 3D was later developed and Land Desktop was retired.

File formats[edit]

AutoCAD's native file formats are denoted either by a .dwg, .dwt, .dws, or .dxf filename extension.

The first file format for 2D and 3D drawing information created with AutoCAD is .dwg. While different third-party CAD software applications can create .dwg information, AutoCAD uniquely creates RealDWG files.[17]

Using AutoCAD, any .dwg file could also be saved to a derivative format. These derivative codecs include:

- Drawing Template Files .dwt: New .dwg are created from a .dwt file. Although the default template file is acad.dwt for AutoCAD and acadlt.dwt for AutoCAD LT, custom .dwt information may be created to include foundational configurations akin to drawing items and layers.- Drawing Standards File .dws: Using the CAD Standards feature of AutoCAD, a Drawing Standards File may be associated to any .dwg or .dwt file to enforce graphical standards.- Drawing Interchange Format .dxf: The .dxf format is an ASCII illustration of a .dwg file, and is used to switch information between numerous functions.[18]
Variants[edit]

AutoCAD LT[edit]

AutoCAD LT is the lower-value model of AutoCAD, with lowered capabilities, first released in November 1993. Autodesk developed AutoCAD LT to have an entry-degree CAD bundle to compete in the lower price stage. Priced at $495, it grew to become the primary AutoCAD product priced beneath $1000. It was offered directly by Autodesk and in pc shops not like the full model of AutoCAD, which have to be purchased from official Autodesk dealers. AutoCAD LT 2015 introduced Desktop Subscription service from $360 per year; as of 2018, three subscription plans had been out there, from $50 a month to a 3-year, $1170 license.

While there are a whole bunch of small differences between the full AutoCAD package and AutoCAD LT, there are a few acknowledged main variations[19] within the software program's features:

- 3D capabilities: AutoCAD LT lacks the flexibility to create, visualize and render 3D fashions as well as 3D printing.- Network licensing: AutoCAD LT can't be used on multiple machines over a community.- Customization: AutoCAD LT doesn't help customization with LISP, ARX, .Net and VBA.- Management and automation capabilities with Sheet Set Manager and Action Recorder.- CAD requirements administration instruments.
AutoCAD Mobile and AutoCAD Web[edit]

AutoCAD Mobile and AutoCAD Web (previously AutoCAD WS and AutoCAD 360)[20] is an account-primarily based mobile and net utility enabling registered customers to view, edit, and share AutoCAD recordsdata via mobile gadget and web[21] utilizing a limited AutoCAD function set - and utilizing cloud-saved drawing information. This system, which is an evolution and combination of earlier merchandise, uses a freemium enterprise model with a free plan and two paid levels, together with various amounts of storage, tools, and online entry to drawings. 360 consists of new options resembling a "Smart Pen" mode and linking to third-get together cloud-based mostly storage similar to Dropbox. Having evolved from Flash-based software program, AutoCAD Web makes use of HTML5 browser expertise available in newer browsers together with Firefox and Google Chrome.

AutoCAD WS began with a model for the iPhone and subsequently expanded to incorporate versions for the iPod Touch, iPad, Android phones, and Android tablets.[22] Autodesk released the iOS model in September 2010,[23] following with the Android model on April 20, 2011.[24] This system is obtainable by way of obtain without charge from the App Store (iOS), Google Play (Android) and Amazon Appstore (Android).

In its initial iOS version, AutoCAD WS supported drawing of lines, circles, and different shapes; creation of textual content and remark containers; and management of coloration, layer, and measurements - in both landscape and portrait modes. Version 1.3, launched August 17, 2011, added help for unit typing, layer visibility, space measurement and file administration.[21] The Android variant includes the iOS characteristic set along with such unique options as the ability to insert textual content or captions by voice command in addition to manually.[24] Both Android and iOS variations enable the user to avoid wasting recordsdata on-line - or off-line in the absence of an Internet connection.[24]

In 2011, Autodesk introduced plans to migrate the vast majority of its software program to "the cloud", starting with the AutoCAD WS mobile utility.[25]

In keeping with a 2013 interview with Ilai Rotbaein, an AutoCAD WS product manager for Autodesk, the identify AutoCAD WS had no definitive that means, and was interpreted variously as Autodesk Web Service, White Sheet or Work Space.[26] In 2013, AutoCAD WS was renamed to AutoCAD 360.[27] Later, it was renamed to AutoCAD Web App.

Student versions[edit]

AutoCAD is licensed, for free, to students, educators, and instructional institutions, with a 12-month renewable license out there. Licenses acquired earlier than March 25, 2020 were a 36-month license, with its last renovation on March 24, 2020.[28] The scholar model of AutoCAD is functionally an identical to the full industrial model, with one exception: DWG files created or edited by a scholar model have an inside bit-flag set (the "academic flag"). When such a DWG file is printed by any model of AutoCAD (industrial or pupil) older than AutoCAD 2014 SP1 or AutoCAD 2019 and newer, the output features a plot stamp/banner on all 4 sides. Objects created in the Student Version can't be used for business use. Student Version objects "infect" a commercial version DWG file if they're imported in variations older than AutoCAD 2015 or newer than AutoCAD 2018.[29]

Ports[edit]

Windows[edit]

AutoCAD Release 12 in 1992 was the first version of the software to assist the Windows platform - in that case Windows 3.1. After Release 14 in 1997, support for MS-DOS, Unix and Macintosh were dropped, and AutoCAD was exclusively Windows supported. Usually any new AutoCAD model helps the present Windows model and some older ones. AutoCAD 2016 to 2020 help Windows 7 as much as Windows 10.[30]

Mac[edit]

Autodesk stopped supporting Apple's Macintosh computers in 1994. Over the next several years, no suitable variations for the Mac have been released. In 2010 Autodesk introduced that it would once once more help Apple's Mac OS X software program in the future.[31] A lot of the features found in the 2012 Windows version may be found in the 2012 Mac model. The principle distinction is the consumer interface and layout of this system. The interface is designed in order that users who're already acquainted with Apple's macOS software program will discover it just like different Mac purposes.[23] Autodesk has also built-in various features as a way to take full benefit of Apple's Trackpad capabilities in addition to the total-display mode in Apple's OS X Lion.[22][23] AutoCAD 2012 for Mac helps both the enhancing and saving of information in DWG formatting that may enable the file to be suitable with other platforms apart from macOS.[22] AutoCAD 2019 for Mac requires OS X El Capitan or later.

AutoCAD LT 2013 was obtainable via the Mac App Store for $899.99. The complete-featured version of AutoCAD 2013 for Mac, nevertheless, wasn't out there via the Mac App Store on account of the value restrict of $999 set by Apple. AutoCAD 2014 for Mac was obtainable for purchase from Autodesk's web site for $4,195 and AutoCAD LT 2014 for Mac for $1,200, or from an Autodesk authorized reseller.[31] The most recent version obtainable for Mac is AutoCAD 2022 as of January 2022.
