# 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. |
| Added the filename to the journal when exporting to IFC if the default is used. |
| 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. |
