Det finns nu en uppdaterad IFC plugin till Autodesk Revit. Du hittar länken HÄR.
The IFC for Autodesk® Revit® 2015 contains up-to-date improvements on the default IFC import and export capabilities of Revit contributed by Autodesk and our Open Source contributors. This app also includes an alternate UI for the export that has extra options from the default.
While this app is not necessary for IFC support, it is recommended that users that depend on the quality of their IFC files download this app and keep it up-to-date, as new enhancements and defect fixes are added, for more information on IFC, please visit the building SMART website (http://buildingsmart.org) or the Revit wiki (http://wikihelp.autodesk.com/enu).
