Autodesk Revit Architecture often referred to as simply Revit is a Building Information Modeling software developed by Autodesk. It 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 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.

Revit is intended to be a major component in Building Information Modeling. A main function of Revit is to eliminate redundancies such as having multiple models across industries. Currently, architects, consultants, general contractors, and manufacturers all create their own models and databases from information handed down in a chain of command. BIM intends to replace this approach with a more centralized one. Revit models created in different disciplines (Architectural, Structural, and Mechanical) can be linked and/or combined into one model. This allows a single model and associated database to be kept, ensuring that all parties have the latest information and that there are no errors in translation. Revit also utilizes its rendering engine to remove the interpretation from complex geometries, allowing more intricate designs to be made and understood.
