IFC vs. RVT: Open Exchange vs. Native Revit (2026)
IFC vs. RVT explained — open buildingSMART exchange vs. native Revit format; fidelity, interoperability, and how to use each correctly.
IFC vs. RVT: Open Exchange vs. Native Revit (2026)
Direct answer
RVT is Autodesk Revit's native, proprietary file format — full parametric fidelity, but only fully usable in Revit. IFC (Industry Foundation Classes) is the open, vendor-neutral buildingSMART standard for exchanging BIM data between different tools. Use RVT to author and store your working Revit model; use IFC to hand the model to teams on other platforms. IFC carries geometry and data well but is not a lossless round-trip of native parametric behavior.
Key facts
| Metric | Value | Notes |
|---|---|---|
| RVT | Native Revit format | proprietary, full fidelity |
| IFC | Open exchange standard | buildingSMART, vendor-neutral |
| Round-trip | IFC not lossless | treat as reference |
| Use | Author in RVT, exchange in IFC |
Side by side
| Dimension | RVT | IFC |
|---|---|---|
| Owner | Autodesk (proprietary) | buildingSMART (open) |
| Purpose | Native authoring/storage | Cross-tool exchange |
| Fidelity | Full parametric | Geometry + data; not lossless round-trip |
| Editable | Fully, in Revit | As reference in other tools |
| Interoperability | Revit ecosystem | Vendor-neutral |
How to use each
Author and store in RVT if you're a Revit shop. When you hand the model to a team on another platform, export IFC — and agree the schema version and MVD so the exchange carries what they actually need.
Common mistake
Treating a received IFC as if it were a native editable model. It is a coordination reference; model your own native elements against it rather than expecting full parametric behavior.
Frequently asked questions
Is IFC a replacement for RVT?
No. IFC is an exchange format for moving BIM data between different tools, not a working authoring format. You keep authoring in RVT (or your platform's native format) and export IFC to coordinate with others. Treat received IFC as a reference model rather than fully editable native geometry.
Does exporting to IFC lose information?
It can. IFC carries geometry and a great deal of data reliably, but native parametric behavior and some app-specific details do not always survive a round-trip. Agree the IFC version and Model View Definition (MVD) up front and validate the export against what the recipient needs.
Why use IFC at all if RVT is higher fidelity?
Because not everyone uses Revit. IFC is the neutral standard that lets an ArchiCAD, Vectorworks, or Tekla team coordinate with a Revit team. Its value is interoperability and open, long-lived data — not replacing the native model.
