And all the BIM-data is exportet on the floors and slabs. But ive done "Modify Sub Elements" on some of the floors. And when exported as an IFC the BIM-data on the modified floors won't show up. The long list is the goal. All the information and parameters are there on both the floors. Its only the Modify Sub Elements that sets them apart.&nbsp;</P> Tue, 15 Oct 2024 13:17:34 GMT anna_gustavsson 2024-10-15T13:17:34Z https://forums.autodesk.com/t5/revit-structure-forum/data-lost-in-ifc-export-for-modify-sub-element-floors/m-p/13085505#M1917 <P>Im trying to export an IFC of my project.
