Export Rhino IDs to IFC using GeometryGym

Hi all,

Is there any way to store object’s Rhino IDs (or costum IDs assigned from Grasshopper) when exporting to IFC using GeometryGym? It can be a custom parameter.


The implementation of this is not very obvious to users, but Ifc Objects have an attribute GlobalId
This is an encoded string of a GUID, and the rhino/grasshopper plugin with use the Rhino ID when exported. You can refer to the attached, the global id can be decoded into a GUID and it matches the rhino id.

Is this what you are looking for? You could also in Grasshopper set the Tag attribute with the Rhino id string, or any custom parameter.
