What it means
The Storey elevation missing check
IfcBuildingStorey.Elevation is null
The fix
How to fix Storey elevation missing in your authoring tool
Concrete, tool-specific steps. The check itself is schema-agnostic and works for IFC2x3, IFC4, IFC4x1 and IFC4x3.
| Authoring tool | How to fix |
|---|---|
| Revit | Levels always carry an elevation in Revit; a null usually means a custom export. Verify Levels have numeric elevations and use the default IFC level export. |
| ArchiCAD | Set each story’s elevation in Design ▸ Story Settings so it isn’t null. |
| Tekla | Ensure each level has a defined elevation in the level/grid settings before export. |
| Allplan | Define each storey’s height/elevation in the building structure so it exports a value. |
