What is the RVT file format?
Files with .rvt extension store parametric 3D construction models created with Autodesk Revit, a BIM software. .rvt project files can comprise:
- Floor plans
- Building designs
- Walls, sections and elevations
- Cross-sections and 3D views
.rvt files can be used to generate 3D views of models, as well as edit projects interactively by adding objects and modifying parameters. Information about a model's components is saved as part of each component's own data.
.rvt files also store metadata and other information about projects. .rvt files can be created using premade elements (BIM objects), either created by users or shipped with Revit. They can be opened with Autodesk Revit, Autodesk Viewer (web) and compatible viewers such as Navisworks. Project views may be exported to 2D/3D .dwg files, or to .ifc for exchange with other BIM applications.
Revit was originally developed by Revit Technology Corporation, released in 2000, and acquired by Autodesk in 2002. Revit allows various specialists - architects, structural engineers and MEP engineers - to collaborate on a joint project. Revit runs on Windows only.
Internally, .rvt uses a Microsoft OLE2 Compound File Binary (Structured Storage) container - the same D0 CF 11 E0 header found in legacy .doc and .xls files. Revit-specific model database streams, geometry, parameter data and an embedded preview thumbnail are stored inside. A BasicFileInfo stream (UTF-16) records the exact Revit build version. Each yearly Revit release bumps the format version; files saved in a newer version cannot be opened by an older one.
Security & safety
RISK: LOWAn RVT is a passive data file and does not execute code, so the file itself is low risk. The practical dangers are workflow, not malware: (1) opening an RVT in Revit upgrades it to that version permanently and it can no longer be opened by older Revit - always keep a backup before opening someone else's file; (2) very large central models can be slow or fail to open on underpowered hardware. Download Revit only from Autodesk; "free Revit download" sites often bundle malware or cracked installers.
Format details
in a nutshell- SnagIt capture / misc data files - Rare legacy uses of .rvt exist but are negligible; the dominant meaning is the Autodesk Revit project file.
Programs that open RVT files
Windows4 apps
Autodesk Revit
Paid Open in Revit (File > Open). If the file is newer, you need an equal-or-newer Revit; opening an older file upgrades it permanently.
Autodesk Viewer
Free Upload the .rvt in a browser to view the 3D model and 2D sheets without installing Revit (read-only).
Autodesk Construction Cloud / BIM 360
Freemium Upload to the cloud platform to view, markup and share the model with a team.
Navisworks Freedom
Free Free viewer for coordination; opens NWD/NWC exported from Revit (not the .rvt directly). 
macOS1 app
Autodesk Viewer (web)
Free Revit has no Mac build; use the browser-based Autodesk Viewer, or run Revit in a Windows VM/Parallels/cloud workstation.
Autodesk Viewer
Free Drag the .rvt into the browser viewer for a quick 3D/2D look without any install. Technical details
deep spec| Container format | Microsoft OLE2 / Compound File Binary (Structured Storage) - the same container type used by legacy .doc and .xls files |
| File signature (magic bytes) | D0 CF 11 E0 A1 B1 1A E1 at byte offset 0 (generic OLE2 header); Revit identity is confirmed by internal stream names, not the header alone |
| Byte order | Little-endian |
| Encoding | Binary (proprietary) |
| Version identification stream | BasicFileInfo stream (UTF-16 encoded) stored near the file start; records the exact Revit build number and format version that wrote the file |
| Internal compression | Proprietary per-stream compression of model data; the file is not a ZIP or other standard archive format |
| Encryption | None by default; file integrity relies on internal format-version consistency checks rather than cryptographic protection |
| Typical file size | 5 MB - 1 GB+ (large multi-discipline central models routinely exceed 1 GB) |
| Associated operating system | Windows only - Revit has no macOS or Linux build |
| Version backward compatibility | Strictly one-way: a file saved in a newer Revit version cannot be opened by any older version; the format version increments with each yearly release |
| Coordinate precision limit | Model elements must remain within approximately 33 km (20 mi) of the internal project origin to maintain coordinate precision |
| Embedded content | Parametric element database, geometry streams, material data, annotations, sheets, schedules, and a preview thumbnail bitmap |
| MIME type | application/octet-stream (unofficial: application/vnd.autodesk.revit) |
| Multi-user collaboration | Worksharing: a central .rvt file on a shared server; team members check out and edit elements via synchronized local copies |
| Open interchange export | IFC (.ifc) for cross-platform BIM exchange; also exports to .dwg, .nwc/.nwd (Navisworks Cache/Document) |
| Related Revit file types | .rfa (Revit Family), .rte (Revit Project Template), .rft (Revit Family Template) |
| Released | 2000 (Revit 1.0 by Revit Technology Corporation; Autodesk acquired Revit in 2002) |
| Latest version | Revit 2026 file format (released April 2025); format version is bumped roughly yearly |
