Most architecture firms use Revit for the initial stages of the design process, Bernstein said, eventually shifting data to AutoCAD to produce the blueprints most contractors and clients still demand. "The relationships there are really critical, and the view in Revit tells you a lot more about what's going on."

"There are places in a building where the systems converge-like the roof and the walls and electrical and ventilation systems," Bernstein said. The design document is also richer, giving viewers a three-dimensional image of the building that gives much more information than a flat representation. Revit lets architects alter designs more efficiently and allows them to reuse design elements, Bernstein said. Even something as basic as calculating the rentable area in a building had to be done by hand." "Those were all things that were estimated by wild-to-educated guess before. "The architect can very easily say, 'You've got this many yards of Sheetrock this much concrete,'" Bernstein said. Revit also automatically keeps track of building materials. A door added to a design, for example, will be accompanied by specifications stored in a database accessible to contractors and others. Instead of simply creating lines and curves, Revit recognizes different elements of a building and applies appropriate logic to them, said Phil Bernstein, Autodesk vice president. Rather than producing paper design documents, a task most commonly done with Autodesk's AutoCAD drafting software, Revit creates electronic design documents that contain much more information than paper allows. Revit, which Autodesk acquired last year with its buyout of Revit Technology, has become a centerpiece of Autodesk's campaign to shift the architecture and construction industries away from blueprints.

Drafting and design software maker Autodesk released a new version Wednesday of Revit, the company's software for creating 3D building designs.
