Research direction

Start with the attached transfer files and the behavior described for beams whose family allows conic shapes, comparing IFC2x3 and IFC4x3 exports in Revit 2025.3.x with IFC for Revit 25.4.0. Review related issue #896 and verify completion by confirming the exported boolean result is no longer inverted.
