The fix
How to fix Empty storey 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 | Delete unused Levels, or check that elements meant for that Level are assigned to it (not a neighbouring Level). |
| ArchiCAD | Remove the unused story or reassign elements’ Home Story so the storey isn’t empty. |
| Tekla | Remove the empty level from the export or reassign parts to it. |
| Allplan | Delete the empty storey node or reassign objects to it. |
How it works
Find and fix it in the browser
The whole flow runs client-side — your IFC file never leaves your machine.
01
Open your IFC file
Open IFC Viewer Online and drag & drop your IFC file. It is parsed locally in your browser via WebAssembly — nothing is uploaded.
02
Run the Health Score validation
Run validation. The "Empty storey" check (RULE_EMPTY_STOREY) flags every affected element and pinpoints it in the model tree.
03
Re-validate
Re-export from your authoring tool and re-run validation to confirm the issue is resolved and your Health Score improved.
