From 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 Eastman C. 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. 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. The concept of bi-directional associativity  between components, views, and annotations was a distinguishing feature of Revit for many releases. The ease of making changes inspired the name Revit, a contraction of Revise-Instantly. 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 company was renamed Revit Technology Corporation in January Revit version 1.

Microsoft Internet Explorer 7. This estimate is based on internal testing and customer reports. Individual models will vary in their use of computer resources and performance characteristics. Models created in previous versions of Revit software products may require more available memory for the one-time upgrade process.
