Definition from buildingSMART: The element type (IfcRampFlightType) defines a list of commonly shared property set definitions of a ramp flight and an optional set of product representations. It is used to define an ramp flight specification (i.e. the specific product information, that is common to all occurrences of that product type).
NOTE: The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which gets assigned by an element occurrence instance through the IfcShapeRepresentation.Item being an IfcMappedItem.
A ramp flight type is used to define the common properties of a certain type of a ramp flight that may be applied to many instances of that type to assign a specific style. Ramp flight types may be exchanged without being already assigned to occurrences.
The occurrences of the IfcRampFlightType are represented by instances of IfcRampFlight.
