IfcFluidMovingDevice

Definition from IAI: IfcFluidMovingDevice is an apparatus used distribute, circulate or perform conveyance of fluids, including liquids and gases, and typically participates in a flow distribution system (e.g., pump, fan).

IfcFluidMovingDevice is a container entity that aggregates all components of the device it represents. The aggregation is handled via the IfcRelAssemblesElements relationship.

HISTORY: New entity in IFC R2x.
ISSUES: See issues and change log for changes made in IFC R2x.

Geometry Use Definitions

The geometric representation of IfcFluidMovingDevice is given by the IfcProductDefinitionShape, allowing multiple geometric representations. Included are:

Local Placement

The use of local placement is defined at the supertype IfcDistributionFlowElement.

Standard Geometric Representation

The use of Standard Geometric Representations is defined at the supertype IfcDistributionFlowElement.
