What it means
The LOD Pset missing check
Element missing required property sets for the declared LOD level
The fix
How to fix LOD Pset 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 | Map the LOD-required parameters to their Psets via a User Defined PropertySets file in the IFC export, and ensure the elements actually carry those parameters. |
| ArchiCAD | Define the LOD Psets in the Property Manager, assign them to the relevant classifications, and map them in the IFC Translator. |
| Tekla | Add the LOD-required properties as UDAs and map them to the Psets in the export. |
| Allplan | Create the LOD attributes and map them to the required Psets in the IFC export. |
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 "LOD Pset missing" check (RULE_LOD_PSET_MISSING) flags every affected element and pinpoints it in the model tree.
