A ramp comprises a single inclined segment, or several inclined segments that are connected by a horizontal segment, refered to as a landing. A ramp flight is the single inclined segment and part of the ramp construction. In case of single flight ramps, the ramp flight and the ramp are identical.
NOTE A single flight ramp is represented by an IfcRamp instance without using aggregation and by utilizing the product shape representation directly at IfcRamp.
An IfcRampFlight is an aggregated part of an IfcRamp realized through the IfcRelAggregates relationship, the ramp flight is therefore included in the set of IfcRelAggregates.RelatedObjects.
An IfcRampFlight connects the floor slab of zero to two different storeys (or partial storeys or landings) within a building. The connection relationship between the IfcRampFlight and the IfcSlab can be expressed using the IfcRelConnectsElements relationship.
