Hi,
Unfortunately the IFC add-on can interpret the “Reveal” tab page only. The IFC windows use this tab page. The “Tilt-Turn Window Setting” is not interpreted by the IFC yet, because the opening geometry can be more sophisticated, then an extruded geometry in general case, what is not supported by other application. It was an agreement of usage of extruded geometry for opening in the IFC ISG (Implementers Support Group). If we might export BREP geometry for opening, then the next problem would be the conversion of BREP to ArchiCAD wall hole in import phase. But we are working on making closer the IFC model to ArchiCAD model. Thank you for your report.
Best regards,
Gyula Kiss
