Limitation

The following 3DEXPERIENCE objects cannot be created (IFC 2x3 and IFC 4). ElementAssembly objects are created instead.

  • 3DEXPERIENCE objects Piping:
    • Piping Instrument
    • Piping Gasket
    • Piping Olet
    • Piping Flange
    • Piping Coupling
    • Piping Reducer
  • 3DEXPERIENCE objects HVAC:
    • HVAC Saddle
    • HVAC Gasket
    • HVAC Instrument
    • HVAC Flange
    • HVAC Reducer
    • HAVC Access Cover

If they cannot be identified:

  • Piping Fitting is mapped to a Piping Miscellaneous.
  • Piping Segment is mapped to a Piping Rigid Pipe.
  • HVAC Fitting is mapped to a HVAC Miscellaneous.
  • HVAC Segment is mapped to a HVAC Rigid Duct.
  • Raceway Fitting is mapped to Raceway Miscellaneous.
