A common misconception is that Autodesk wants to undermine IFC. There is a lot of mud throwing between ADSK users and IFC zealots. Looking at the improvements ADSK is making to better support open standards like IFC. I would like to add my bit to the big discussion. (everything written in blue is mine the rest is provided by Autodesk)
This information comes from Autodesk.
Autodesk Revit 2013 is:
This information comes from Autodesk.
Autodesk Revit 2013 is:
- IFC v2x3 certification ( re-certified)
- IFC export Add-In supporting 2×4 standard
- Increased IFC open source customization : creation of own features possible
- Local IFC requirements differs
- Autodesk committed for IFC : full team works on this
- New element types can now be exported
- Support for workflows
- Export as solids : more possibilities
More elements supported for export
.NET Open Source code released for Quasar
2D Plan view export no longer offset from 3D Geometry
Always export True North to IFC
Beam Length fixed for certain beams on export
Beams never extruded upwards
Better Geometry splitting for elements allows for fewer surface models
Coordination View 2.0 (CV2) improvements
IFC export has added a number of improvements for Coordination View 2.0.
“Current View Only” export now works in any model view
“Current View Only” mode has been fixed and now has extra functionality.
Doors with nested openings export opening
Export Assemblies
Export PSet_BuildingCommon
Export Filled Regions
Export Parts
Export Uniformat information as IfcClassification and fcClassificationReference
GSA export support
IFCExportAs shared parameter accepts “IfcWallStandardCase” as valid value
Internal Revit property set names no longer have “PSet_Revit_” prefix on export
Light Source no longer exported for lighting fixtures
MEP Plumbing Fixtures exported as IfcFlowTerminal
Multi-story stairs have correct properties
Postal Address is parsed in the Location
Slab base quantities are only exported for COBIE or QTO
Split by level option exports geometry below the lowest level
Unit specification for Mass corrected
Import
Fix normal of slightly non-planar faces
Prevent creation of illegal faces in imported geometry
Space geometry not imported as in-place family solid
Text Font not always set correctly
But more important is that Autodesk made an api for ifc so everyone could create their own importer / exporter if needed.
next to that:
BuildingSMART International Industry Foundation Classes (IFC) version 2×3 is now certified for Revit. Revit supports global industry standards including GSA specific classifications and property sets for building management and energy analysis. Open source Revit IFC exporter enables you to submit updates and at any time the exporter can be updated to support emerging standards.
The BIM Open Source Project now controls the code for the Revit STL and IFC Exporter. You can propose changes to the IFC exporter, fix bugs, or enhance the code base to support regional requirements, allowing you to collaborate more effectively with third-party applications to support design workflows.
Bottom Line: Industry Foundation Classes (IFC) for Revit provides greater support for industry and government standards.
Conclusion we are not the enemy 🙂
Revit and IFC
Excellent blog
Interesting you have stated revit can export parts in IFC format – can you provide some info in this and the required IFC classification.
Cheers

Hello Graham,
I looked into your question and here is some more information. I created an extra blog post for the subject:
I am not entirely sure about the required IFC classification.
