Which file extension is associated with Revit project files?

The file extension associated with Revit project files is .rvt. This extension indicates that the file is a native project file created and used by Autodesk Revit, which is specifically designed for Building Information Modeling (BIM). The .rvt format allows Revit to store not only geometric information but also data related to building elements, views, schedules, and other project-specific information, facilitating collaborative work within an integrated environment.

In contrast, the other file extensions pertain to different types of files. The .dwg extension, for instance, is commonly associated with AutoCAD files, which are primarily used for 2D and 3D design and drafting. The .dxf format is derived from .dwg and is used for data interoperability, typically to allow files to be shared between different CAD software. Lastly, the .fbx file format is utilized for exchanging 3D models and animations but is not specific to Revit. Each of these extensions serves different purposes and is associated with specific software applications beyond the scope of Revit.
