Why are some Revit custom parameters missing in my exported IFC file?

Revit requires an export mapping configuration (such as "Export user-defined property sets") to translate custom family parameters into standard IFC Property Sets (Pset).

Can I open and inspect an IFC file without buying expensive software?

Yes. Free tools like BIMcollab Zoom, open-source Bonsai (BlenderBIM), and Trimble Connect allow you to view 3D IFC models and inspect property sets with zero subscription fees.

Should I convert Revit to IFC, or downgrade to an earlier Revit version?

If you are exchanging building models with non-Autodesk platforms (like ArchiCAD, Vectorworks, or Solibri), IFC is the openBIM standard. However, if your recipient is also using Autodesk Revit but on an older version (e.g. Revit 2023 or 2024), exporting to IFC turns your parametric families into uneditable direct shapes. In that scenario, using a native downgrade tool like RVT Convert preserves native Revit parameters, schedules, and dimensions.

Autodesk Revit (.rvt) to IFC openBIM Standard Converter

Autodesk Revit is the market leader for architectural BIM, but public infrastructure projects, government tenders (such as UK BIM Mandate and Singapore CORENET X), and MEP subcontractors require vendor-neutral IFC files for Solibri clash detection or Archicad federation. Converting RVT to certified IFC enables friction-free openBIM collaboration across the global construction industry.

Confidential IP & Safety Warning

Custom in-house Revit shared parameters will NOT export to IFC unless you configure a custom Property Set mapping file (userdefinedpropertysets.txt). Always verify that non-standard BIM parameters are mapped to valid Pset_ structures.

Select the Appropriate Model View Definition (MVD)

Choose IFC2x3 Coordination View 2.0 if sharing with external structural engineers using legacy software. Choose IFC4 Design Transfer View if the recipient needs to perform direct parametric geometry editing.

Configure Shared Parameter Export Mapping Tables

Revit stores parameters internally. Use an external parameter mapping text file to map internal family parameters to official buildingSMART Property Sets (Pset_WallCommon, Pset_DoorCommon).

Align Shared Project Coordinates (Base Point / Survey Point)

Ensure the export coordinate system is set to Shared Coordinates. Mismatched origin points will cause architectural and MEP models to load hundreds of meters apart in federated Navisworks sessions.
