IFC4 MVD Comparison

This page compares the two successors of the IFC2x3 Coordination View V2.0 that have been developed for IFC4.

comparison of the objectives and target work flows
IFC4 Reference View IFC4 Design Transfer View

goals

  • satisfy the referencing work flow, i.e. the result of the import is a “read-only” (not modifiable)

 

  • satisfy the handover work flow, i.e. import for further editing (import into native elements)

scenario includes

  • background reference
  • clash detection
  • any viewer based work flow

 

  • takeover architecture in structural
  • import spaces into MEP
  • takeover a previous design

expected user experience

  • ownership remains with the sender
  • frequent updates
  • fast export / import times
  • 100% validity, no rework expected

 

  • ownership handed over to receiver
  • low frequency, sometimes “one of”
  • longer export / import time tolerable 
  • some rework accepted, if limitations well known

 

detailed entity comparison table

Included in the comparison are:

  • IFC2x3 CV2 - IFC2x3 Coordination View Version 2.0
  • IFC4 RV - IFC4 Reference View (currently RC1)
  • IFC4 DTV - IFC4 Design Transfer View (currently beta)
