RTE, Revit Project Template (.rte)
The RTE Data file format
RTE is the file extension given to files created in Revit. Revit is a design program specifically for 3D models. Project templates created in this program are saved as RTE files. They contain so-called BIM information, which stands for building information modeling. On the basis of the RTE files, users of Revit can create several projects that use the same layout. These projects are saved as RVT files.
Technical details of RTE files
When altering or saving an RTE file, the program will prompt users to enter a new file name, thus creating a new template file instead. Templates cannot be overwritten, hence why the program is prohibiting users to erase or replace an already existing template.
