Flow controller

Definition

Controller in an HVAC system, e.g. air terminal box, damper or valve.

2D Geometry

• Flow controllers don't have any geometry use definitions, and consequently the geometry does not have any semantics. The geometry is purely for representation purposes.
• As the basic representation the bounding box should be provided.
• Brep geometry may be used for the 3D representation
• 2D geometry may be used for the symbolic 2D representation.

View considerations

• Arch. design >> Quantities take off / cost estimating
  • Count
  • Type
  • HVAC system
  • Extension PropertySet defined by Visio.
• No connectivity information (network topology)
