6.1.3.25 IfcRampFlight
6.1.3.25.1 Semantic definition
A ramp comprises a single inclined segment, or several inclined segments that are connected by a horizontal segment, referred 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.
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.

Axis 2D Geometry | General |
The walking line is represented by a two-dimensional open curve as the axis. The curve is directed into the upward direction (direction has to be interpreted as specified at the subtypes of IfcCurve). Figure 6.1.3.25.D illustrates the axis representation which has the following constraints:
