AutoCAD put drafting on the personal computer: how Autodesk changed design software

Autodesk was founded in 1982 as personal computers were beginning to create new opportunities for professional software.

That same year, AutoCAD was introduced to the market. Its importance was not simply that it could create technical drawings digitally. Autodesk was part of a broader shift that moved computer-aided design away from expensive specialist computer systems and towards the emerging personal-computer market.

More than four decades later, Autodesk has expanded far beyond AutoCAD. Its software now covers architecture, engineering, construction, manufacturing, product design, media and entertainment, while AutoCAD remains one of the products most closely associated with the company.

AutoCAD helped move CAD onto personal computers

Before the personal-computer era, computer-aided design systems were commonly associated with expensive specialist hardware.

Autodesk approached the market differently.

AutoCAD was demonstrated in 1982 and was designed to operate on the increasingly accessible computer hardware of the period. Autodesk’s own historical material describes the company’s early ambition as bringing CAD from expensive computer systems to the PC.

The first version was extremely small by modern standards. Autodesk says AutoCAD 1.0 required around 128KB of memory, contained roughly 12,000 lines of source code and originally carried a US list price of about $1,000.

Those numbers are interesting today, but the more important change was accessibility.

Architects, engineers and designers increasingly had the ability to create, modify and reproduce technical drawings using general-purpose computers instead of relying exclusively on specialised CAD systems.

AutoCAD became the product most closely associated with Autodesk’s early growth.

Autodesk went public in 1985

Autodesk completed its initial public offering in 1985.

Company filings show that Autodesk’s shares originally traded on Nasdaq under the symbol ACAD before the company later adopted the ADSK ticker.

Going public came only a few years after Autodesk’s founding and AutoCAD’s introduction, reflecting how quickly the personal-computer software industry was developing during the 1980s.

Autodesk subsequently expanded its product range well beyond two-dimensional drafting.

Autodesk expanded from drafting into 3D design and modelling

As computer hardware became more capable, design software increasingly moved beyond electronic versions of traditional drawings.

Autodesk expanded into areas including 3D modelling, mechanical design, building information modelling, animation and visual effects.

Some of that expansion came through Autodesk’s own product development, while important parts also came through acquisitions.

One major example was Revit.

Autodesk announced its intention to acquire Revit Technology Corporation in February 2002 and completed the acquisition in April that year. Revit brought parametric building-modelling technology into Autodesk’s portfolio and became one of the company’s most important products for architecture, engineering and construction.

Another significant expansion took place in January 2006 when Autodesk completed its acquisition of Alias.

Alias brought technology used in industrial design, visualisation and digital entertainment. Its portfolio included Maya, which became part of Autodesk’s media and entertainment software business.

Alongside products such as 3ds Max and Inventor, these additions helped transform Autodesk from a company identified primarily with AutoCAD into a much broader design-software business.

Revit helped make building information modelling central to Autodesk

Traditional CAD drawings describe individual elements of a design, but building information modelling takes the concept further by allowing designers to work with an information-rich digital representation of a building.

Revit became central to Autodesk’s position in this market.

Instead of treating plans, sections and other documentation as largely separate drawings, a BIM workflow can connect them to the underlying building model. Changes to the model can then be reflected across related project information.

That approach has become an important part of modern architecture, engineering and construction workflows.

Autodesk moved from perpetual licences towards subscriptions

Another major change came in the way Autodesk sold its software.

For many years, professional software was commonly purchased through perpetual licences. Customers could buy a particular version and continue using that licensed version.

Autodesk began moving towards a subscription-focused business model during the 2010s.

In February 2015, the company announced that new commercial seats of most standalone desktop products would generally be available only through subscription beginning on 1 February 2016.

Autodesk later announced that most Design & Creation Suites and additional products would move to subscription-only availability for new commercial licences after 31 July 2016.

Importantly, this did not invalidate perpetual licences that customers had already purchased. Existing customers could continue using qualifying perpetual licences under the terms that applied to them.

Today, Autodesk sells its current software primarily through subscriptions.

The change created a recurring-revenue business model for Autodesk while also changing the relationship between software vendors and customers. Rather than purchasing a new perpetual version periodically, subscribers receive access to software and updates for as long as their subscriptions remain active.

Autodesk today extends far beyond AutoCAD

AutoCAD remains historically important to Autodesk, but the modern company operates across a much wider range of design and production workflows.

Its products are used in architecture, engineering and construction, product design and manufacturing, and media and entertainment.

Cloud collaboration, shared project data, automation and computational design have also become increasingly important parts of those workflows.

The progression from AutoCAD to products such as Revit, Inventor, Maya and 3ds Max therefore tells a larger story about the evolution of professional design software.

Autodesk began during the personal-computer revolution by helping make computer-aided drafting more accessible. It subsequently expanded into modelling, building information management, manufacturing workflows, animation and cloud-connected design tools.

More than four decades after its founding, AutoCAD remains one of Autodesk’s defining products, but the company built around it has become considerably broader than the drafting program that helped establish its name.
