Problem Exporting from Rhino 8 to IFC

[Axel_Burvall_Terán]

I am trying to export a mesh from Rhino 8 to IFC, using the Geometry Gym plug-in, and following this tutorial:

Rhino to IFC Example | Geometry Gym

I have created a root layer (“Site”), and assigned this as IFcProject. The sublayer containing the object (“Berg”) have been assigned as IfcSite, I have only a single object in the file.

When I try to export to IFC using ggIFCExport, I get the error message “XXX No IfcProject Classification found on nominated Layer!”

What might be the problem here?

If the layer nominated as IfcProject is the active layer, that command should work.

But the easier way to start the export is to right click on the IfcProject layer, and use the context menu as shown in this image.

Let me know if this doesn’t help.
