The fix
How to fix Project has no long name 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 Project Name / Project Issue Name in Manage ▸ Project Information and map it to IfcProject.LongName in the IFC export setup. |
| ArchiCAD | Set the project name/description in File ▸ Info ▸ Project Info; the IFC Translator maps it to IfcProject.LongName. |
| Tekla | Set the project name in Project properties and map it to IfcProject.LongName in the export. |
| Allplan | Set the project name/description in project info so IfcProject.LongName is populated. |
