Autodesk Revit is Building Information Modeling software for Microsoft Windows, currently developed by Autodesk, which allows the user to design with both parametric 3D modeling and 2D drafting elements. Building Information Modeling is a Computer Aided Design (CAD) paradigm that employs intelligent 3D objects to represent real physical building components such as walls and doors. In Revit, views of the building model are cameras, either orthographic or perspective: a component such as a door can be moved in any view, and all other views of the model will update automatically. As each 'view' is a camera of the actual 3D model, a change anywhere is a change everywhere. This is made possible by Revit's underlying relational database architecture which its creators call the parametric change engine. In addition, Revit's database for a project can contain information about a project at various stages in the building's lifecycle, from concept to construction to decommissioning. This is sometimes called 4D CAD where time is the fourth dimension. Autodesk purchased the Massachusetts-based Revit Technology Corporation for $133 million US in 2002. The latest released version is Revit Architecture/Structure/MEP 2011 (April, 2010) and the corresponding AutoCAD Revit Suite 2010 products. (AutoCAD Revit Suite combines a seat of AutoCAD with a seat of Revit on a given workstation for a slightly higher price than Revit alone.) On September 29, 2008, Autodesk released 64-bit versions of Revit 2009 products for subscription customers. 32-bit and 64-bit versions of Revit 2010 & 2011 products are available without subscription. |
