VisibleRefractionIndex

P_SINGLEVALUE / IfcReal

Visible Refraction Index

Index of refraction (visible) defines the "bending" of the sola! r ray in the visible spectrum when it passes from one medium into another.

SolarRefractionIndex

P_SINGLEVALUE / IfcReal

Solar Refraction Index

Index of refraction (solar) defines the "bending" of the solar ray when it passes from one medium into another.

GasPressure

P_SINGLEVALUE / IfcPressureMeasure

Gas Pressure
