What it means
The Missing type check
Element has no IfcTypeObject (IfcWallType, IfcDoorType, …)
The fix
How to fix Missing type 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 | Revit family types export as IfcTypeObjects automatically. Missing types usually mean in-place families or generic models — convert them to loadable families with defined types, and keep type export enabled in the IFC options. |
| ArchiCAD | Use favourites / building materials and keep "Type Product" export enabled in the IFC Translator so element types are written. |
| Tekla | Assign a profile and material so the part exports with a type; verify the IFC export writes type objects. |
| Allplan | Use library objects / SmartParts with defined types and enable type export in the IFC interface. |
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 "Missing type" check (RULE_MISSING_TYPE) flags every affected element and pinpoints it in the model tree.
