📌New in Revit 2026

Improved performance when linking IFC files (up to 50 %)

Advanced positioning options when linking IFC files. The default position places the link's origin at the internal Revit origin.

Full list of Enhancements:

Allowed groups to be exported as all IfcSystem types in IFC4.3 (and previous) versions.
Added angle units for some exported IFC files that only contained calculated angle values.
Implemented the ability to add type properties to instance properties for user-defined property sets.
Stabilized some IFC GUIDs when exporting some beams and ramps to IFC.
Added real Revit parameter groups to the UI.
Moved checkboxes in data grids to a column on the left side of grid.
Implemented filtering of common property sets not marked for export at the property set level.
Added the ability to select a scheme.
Added options to allow the user to control where IFC files are linked.
Implemented generation of a list with all available property sets dependent on chosen schema for IFC Common Property Sets.
Implemented generation of list box property sets depending on selected setup and IFC schema.
Added the ability to associate the IfcSpatialContainer shared parameter to levels, so that all elements associated with that level can optionally be mapped to a different level.
Allowed export of map conversion scale attribute to IFC.
Improved linking of IFC files that contain large coordinates.
Added the ability to optionally export ceiling grids to IFC as a footprint representation.
Fixed a validation issue for Schema Entity Rule - IfcShapeModel.WR11 for 2x3, IFC4, 4x3.
Updated the export of the Uniformat classification information to IFC to comply with bSDD requested source data.
Allowed export of material constituent fraction to IFC.
Fixed IfcProductDefinitionShape.ShapeOfProduct.
Fixed Entity Rule - IfcShapeModel.WR11.
Added the ability to control the entity type of wall parts when exporting to IFC.
Added a tooltip for the "Use Active View when Creating Geometry" option when exporting IFC files.
Improved the description and tooltips for IFC menu items.
Removed deprecated attributes LandTitleID /SiteAddress in IFC4.3, supported by Pset_LandRegistration and Pset_Address instead.
Added API to get and set the tooltip description for shared parameters.
Enhanced logging of the ODA uninitialization process.
Improved positioning of linked instances when exporting to IFC.
Improved filtering of sub-categories in the IFC category mapping dialog when the list of sub-categories was collapsed and re-expanded.
Improved linking of IFC files that have modified North direction.

Fixed IFC / Antlr build warnings in Revit.sln.
Added IfcAnnotation as an option for element and category mapping when exporting lines and site property lines to IFC only.
Added the ability to export Site property lines to IFC.
Added a validation check and warning if an invalid category mapping template is imported.
Improved the UI for validation in the Category Mapping dialog.
Added minor improvements to the Export IFC Category Mapping dialog.
Improved export of a few material properties to IFC.
Improved performance while linking IFC files.
