The fix
How to fix Empty property value 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 | Find the parameter and enter a value (or remove the empty parameter). A schedule is the fastest way to find and fill blanks in bulk. |
| ArchiCAD | Use the Property Manager or an interactive schedule to find and populate empty property values. |
| Tekla | Populate the empty UDA values via the inquire/report tools before export. |
| Allplan | Fill the empty attribute values via the attribute palette or a list before 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 "Empty property value" check (RULE_EMPTY_PROPERTY_VALUE) flags every affected element and pinpoints it in the model tree.
