What is a RFA file?
The .RFA file extension is primarily a Revit Family File. Autodesk Revit uses these files to store 3D models and data for building elements like doors, windows, and furniture. A smaller number of .RFA files might be Battlefield 1942 Game Packages used by Electronic Arts.
How to open RFA files?
You can open standard Revit Family Files using Autodesk Revit or view them with tools like Autodesk Navisworks. If the file is a game package, players use community tools to extract the game audio and textures.
Software and tools
Professionals use AutoCAD and Revit to manage these 3D assets. Because the extension has multiple possible meanings, viewer.online/rfa is a helpful tool. It analyzes .RFA files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Summary
Because the primary .RFA files use the well-known underlying DOC format structure, viewer.online/rfa can safely open and display them online, eliminating compatibility problems.
