Quantities such as length or width or height of a wall can also be specifically written to an IFC file. They are not linked to the geometry of the object, so when meeting such quantities in an IFC file there is no guarantee that they reflect the actual object geometry. However, these quantities allow applications that are not able to process the geometry, such as spreadsheet applications, to know the principal dimensions of objects. You can check which quantities will be exported to IFC using the quantities manager found under menu Manage->IFC quantities.
