How to set the Elevation Attribute for an IFCBUILDINGSTOREY class correctly?
I have a workbench dedicated to write the ifc-file of a building I have created project, site, building, buildingstorey and spaces and related correctly via globalID and parentID. The file will be written and can be opened in most IFC-Viewer applications. BUT:
even though I have created an attribute named “ifc_elevation” and set this to be written with the buildingstorey features, it is not written into the STEP-Code (10th attribute of the buildingstorey class). I downloaded the file from the BIMfit-challenge - this does not write the elevation either.
is there a solution, or is FME not capable of writing the elevation -attribute? The screenshot shows the attributes I am sending to the writer.
FME 2026.2 / IFC API writer / IFC 4.3

Thanks a lot in advance for any help!
