In 2013, Autodesk began introducing rental licensing for some of its products, including Revit. It was a feature limited or Lite version of Revit which excluded features such as rendering and multi-user environments. In 2012 Revit LT became the newest version of Revit on the market. This is similar to the way the visual programming language Grasshopper 3d works on objects in Rhinoceros 3D. In 2011 Dynamo was released in beta form allowing first glimpses of directly programming the behavior of hosted components through a drag and drop node interface. After the 2006 release Revit Building was renamed Revit Architecture. In 2005 Revit Structure was introduced, then in 2006 Revit MEP. Īutodesk released several versions of Revit after 2004.

Licensing was controlled by an entirely automatic process, an innovation at a time when human intervention and manual transmission of authorization codes was required to buy other types of design software.

The software was initially offered only as a monthly rental, with no option to purchase. The software progressed rapidly, with version 2.0, 3.0, 3.1, 4.0, and 4.1 released in August 2000 October 2000 February 2001 June 2001 November 2001 and January 2002, respectively. Revit version 1.0 was released on April 5, 2000. The term Parametric Building Model was adopted to reflect the fact that changes to parameters drove the whole building model and associated documentation, not just individual components. At the heart of Revit is a parametric change propagation engine that relied on a new technology, context-driven parametrics, that was more scalable than the variational and history-driven parametrics used in mechanical CAD software. The ease of making changes inspired the name Revit, a contraction of Revise-Instantly. The concept of bi-directional associativity between components, views, and annotations was a distinguishing feature of Revit for many releases. For example, moving a wall updated neighboring walls, floors, and roofs, corrected the placement and values of dimensions and notes, adjusted the floor areas reported in schedules, redrew section views, etc.-so that the model remained connected and all documentation was coordinated. Two key differences in Revit were that users created parametric components in a graphical "family editor" rather than a programming language, and the model captured all relationships between components, views, and annotations so that a change to any element automatically propagated to keep the model consistent. At the time, several other software packages-such as ArchiCAD and Reflex-provided a three-dimensional virtual building model, and let the user control individual components via parameters (parametric components).

With their Revit platform, Autodesk is a significant player in the BIM market together with Bentley Systems and the Nemetschek group (owner of Graphisoft's BIM application ArchiCAD, plus solutions including Allplan and Vectorworks), among others.įrom the outset, Revit was intended to allow architects and other building professionals to design and document a building by creating a parametric three-dimensional model that included both the geometry and non-geometric design and construction information, which is also known as Building Information Modeling or BIM (1975 Eastman C.).
The purchase allowed more research, development and improvement of the software. Autodesk, best known for its AutoCAD line of products, purchased Revit Technology Corporation for US$133 million in 2002. The company was renamed Revit Technology Corporation in January 2000. In 1999 they hired Dave Lemont as CEO and recruited board members Jon Hirschtick, founder of SolidWorks, and Arol Wolford, founder of CMD Group.

With funding from venture capitalists Atlas Venture and North Bridge Venture Partners, Raiz and Jungreis hired several software developers and architects and began developing Revit in C++ on the Microsoft Windows platform. Charles River Software was founded in Newton, Massachusetts, on October 31, 1997, by Leonid Raiz and Irwin Jungreis, key developers of PTC's Pro/Engineer software for mechanical design, with the intent of bringing the power of parametric modeling to the building industry (PTC had previously tried and failed to market its recently acquired Reflex software to the construction sector).
