• Space Boundaries: None
• Split walls, Columns, and Ducts by level
• Export only elements visible in the view
• Export Revit property sets
• Export IFC Common property sets
• Export base quantities
• Export user-defined property sets
• Allow use of mixed “Solid Model” representation
• Use active view when creating geometry
• Use family and type name for reference
• Use 2D room boundaries for room volume
• Include IfcSite elevation in the site's local placement origin
• Store the IFC GUID in an element parameter after export
• Keep Tessellated Geometry as Triangulation
