Hello,
I am trying to export my Revit model to and IFC format with Spot Elevation tags.
I have added my tags in the 3D view as well as in the 2D plan view and in the IFC options I have entered the supporting class for the Spot Elevation (see the attached pictures) I have tried "IfcAnnotation" and "IfcBuildingElementProxy" but nothing exports when I open the IFC in Tekla Bimsight viewer.
I can't find any other Spot Elevation export supporting class and am not sure where is the problem.
P.S. I have managed to export Grids to IFC but the same procedure doesn't work for annotations?
