Hi,
I am trying to use the new functionality in OpenRoads 2024 which is the ifc export mapping option when using Export to IFC function.
I have found very limited documentation on Bentley's help, the most useful document being :

Digital Twins Knowlege Base - Modifying Default Mapping for IFC Exports - Communities

I have got a model set up in ORD using civil Points. These Points are set up with feature definitions, so that they display a plan template and a 3D template that are different. I also have an item type with metadata attached to the feature definition.

When I export to ifc, both 2D symbols and 3D cells transfer in ifc.

I would like to edit the ifc mapping files so the 2D element is not exported, but I can't find the proper syntax to do so. 

How do I know which schema and EC class applies to my elements ? This is a screenshot of the properties in ORD (from the same element in 2D and 3D).

Ideally I would like to use properties from the General section (cell name) for instance to exclude this element using "IGNORETHISCLASS", because the feature definition will be the same for 2D and 3D. 

Does anyone know the syntax to do this or any additional documentation where I can find more information?
Attached my example dgn file fyi and the corresponding ifc using standard mapping file.
Thank you

Elise
