Revit files, which are commonly used in Building Information Modeling (BIM), can be viewed with various software and methods. One of the most popular ways to view Revit files is to use Autodesk's own software, such as Revit Viewer. This tool allows users to open and view Revit files without the need for a full Revit license. Another option is to use other CAD software that supports the .rvt file format, like AutoCAD or Navisworks. These programs enable users to open and review Revit files, as well as perform basic editing and collaboration tasks. In addition to specialized software, there are also online platforms and viewers that allow for easy access to Revit files. For example, BIM 360 Docs provides cloud-based access to Revit files, allowing for viewing and collaboration from any device with an internet connection. Some third-party viewers, like BIMx and the Unity Viewer, also support the viewing of Revit files. Lastly, for simple viewing and sharing, you can convert Revit files to other 3D modeling formats, such as .obj or .fbx, using conversion tools like Autodesk FBX Review. With these techniques and tools, you can easily view and share Revit files for your design and construction projects.
