|Elément de distribution de fluide|
|Komponente der TGA (allgemein) |
The distribution element IfcDistributionFlowElement defines occurrence elements of a distribution system that facilitate the distribution of energy or matter, such as air, water or power.
EXAMPLE Examples of distribution flow elements are ducts, pipes, wires, fittings, and equipment.
HISTORY New entity in IFC2.0.
IFC4 CHANGE Ports are now primarily defined using IfcRelNests to enable definition of ports at type definitions (both forward and backward compatible), provide a logical order, and reduce the number of relationship objects needed. The relationship IfcRelConnectsPortToElement is still supported, however is now specific to dynamically connected ports.
Common Use Definitions
The following concepts are inherited at supertypes:
- IfcRoot: Identity, Revision Control
- IfcElement: Product Placement, Box Geometry, FootPrint Geometry, Body SurfaceOrSolidModel Geometry, Body SurfaceModel Geometry, Body Tessellation Geometry, Body Brep Geometry, Body AdvancedBrep Geometry, Body CSG Geometry, Mapped Geometry
- IfcDistributionElement: Quantity Sets, Spatial Containment
The Object Typing concept applies to this entity as shown in Table 211.
Table 211 — IfcDistributionFlowElement Object Typing
Property Sets for Objects
The Property Sets for Objects concept applies to this entity as shown in Table 212.
Table 212 — IfcDistributionFlowElement Property Sets for Objects
The Axis Geometry concept applies to this entity as shown in Table 213.
Table 213 — IfcDistributionFlowElement Axis Geometry
This represents the 3D flow path of the item having IfcShapeRepresentation.RepresentationType of 'Curve3D' and containing a single IfcBoundedCurve subtype such as IfcPolyline, IfcTrimmedCurve, or IfcCompositeCurve. For elements containing directional ports (IfcDistributionPort with FlowDirection of SOURCE or SINK), the direction of the curve indicates direction of flow where a SINK port is positioned at the start of the curve and a SOURCE port is positioned at the end of the curve. This representation is most applicable to flow segments (pipes, ducts, cables), however may be used at other elements to define a primary flow path if applicable.
The Clearance Geometry concept applies to this entity as shown in Table 214.
Table 214 — IfcDistributionFlowElement Clearance Geometry
This represents the 3D clearance volume of the item having RepresentationType of 'Surface3D'. Such clearance region indicates space that should not intersect with the 'Body' representation of other elements, though may intersect with the 'Clearance' representation of other elements. The particular use of clearance space may be for safety, maintenance, or other purposes.
The Lighting Geometry concept applies to this entity as shown in Table 215.
| ||LightSource|| |
| ||MappedRepresentation|| |
Table 215 — IfcDistributionFlowElement Lighting Geometry
This represents the light emission of the item having IfcShapeRepresentation.RepresentationType of 'LightSource' and containing one or more IfcLightSource subtypes. This representation is most applicable to lamps and light fixtures, however may be used at other elements that emit light.
