openbep (SamuelAB)MCADConfidence: Medium

In a live Revit test, fans, panels and windows failed IDS checks on standard Pset properties like NominalAirFlowRate, RatedCurrent and VisibleLightTransmittance, although the values were in the IFC already under Revit names like Flow, Mains and Voltage. The fix is a mapping file copying each Revit parameter into the standard property.
