How to add quantities to IfcBuilding #268

Open eibre opened 3 years ago

eibre commented 3 years ago

How can we add information to Qto_BuildingBaseQuantities.Height as defined in https://standards.buildingsmart.org/IFC/RELEASE/IFC4/ADD2_TC1/HTML/schema/ifcproductextension/qset/qto_buildingbasequantities.htm.

I have tried to check "Export base quantities" in export settings dialog with no luck. I have also tried to add a parameter to Project Information in revit and used a text file pset mapping in IFC export.

PropertySet:    Qto_BuildingBaseQuantities  I   IfcBuilding
    Qto_BuildingBaseQuantities.Height   Length  m_height

I use Revit 2021 and the latest version of the exporter found here on github under releases.

Hi Einar,

Unfortunately Qto_BuildingBaseQuantities is not yet supported currently. It is mainly because IfcBuilding does not actually have any direct associated representation in Revit. To support properties/quantities related to the Building, they need to be handcrafted in. You can add this as a feature request, but we cannot commit any timeline for this.
