What it means
The No file author check
IFC STEP header FILE_NAME has no author specified
The fix
How to fix No file author 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 | Set the author in the IFC export setup (Modify setup) or in Manage ▸ Project Information; this populates the STEP FILE_NAME author field. |
| ArchiCAD | Set author and company in File ▸ Info ▸ Project Info and the IFC Translator so they are written to the header. |
| Tekla | Set the author/organisation in the IFC export advanced settings. |
| Allplan | Set author/organisation in the project info / IFC export settings. |
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 "No file author" check (RULE_FILE_AUTHOR_MISSING) flags every affected element and pinpoints it in the model tree.
