IfcOpenShell (IfcOpenShell)MCADConfidence: Medium

get_reference_line only looks for wall axes in a Plan context, while Revit and ArchiCAD exports put them under Model. On one Revit export it found none of 2,178 real wall axes, fell back to a 1 m axis, and regenerate_wall_representation silently rebuilt walls from it.
