Annex E Examples - UT_DrainageSystem_2
Example overview
DrainageSystem_2
Intent
This UT implements IfcDistributionSystem for road drainage with a culvert and open side ditches.
It is based on storyline bSFi_IR_SLRD-DD (https://app.box.com/s/x9q3q62tcc77hdqpdw0vjncj7bg3byay).
Prerequisites
This scenario builds upon following other scenarios: - SpatialStructure_4
Content
This scenario covers the following concepts and/or IFC entities:
- spatial structure and containment
- IfcSite
- IfcRoad
- IfcFacilityPart with correct PredefinedType
- IfcRelContainedInSpatialStructure
- IfcRelReferencedInSpatialStructure
- system structure
- IfcDistributionSystem with correct PredefinedType
- IfcRelReferencedInSpatialStructure to assign system to spatial element(s) it services
- IfcRelAssignsToGroup to assign physical elements to the system
- IfcRelNests to relate ports to physical elements
- IfcDistributionPort with correct PredefinedType and FlowDirection
- IfcRelConnectsPorts
- physical elements
- IfcDistributionChamberElement with correct PredefinedType
- IfcPipeSegment with correctPredefinedType
Situation
The start situation is described in the UT SpatialStructure_4 output (SpatialStructure_4.ifc). In addition, UT_DrainageSystem_2_2.xml provides top surface of road structures for reference. The drainage system elements are given in UT_DrainageSystem_2_1.xml. Note: the open ditches are modeled here as LandXML Channel elements, roughly following the correcponding ditch bottom breakline in the surface model, but the number of bends, modeled as Connections, is reduced for practical reasons. Also, the Channel dimensions do not necessarily match the slopes in the surface model.
Expected Results
Physical elements contained/referenced in the spatial structure set in UT SpatialStructure_4.
Should be visualised correctly compared to the supporting screenshots.
Physical elements grouped into one IfcDistributionSystem, which is assigned to IfcRoad.
Network topology using IfcDistributionPort and IfcRelConnectsPorts.
