Class Documentation

class Ifc4::IfcConversionBasedUnitWithOffset : public Ifc4::IfcConversionBasedUnit

IfcConversionBasedUnitWithOffset is a unit which is converted from another unit by applying a conversion factor and an offset.

HISTORY New entity in IFC 2x4.

Example: The temperature unit Fahrenheit is based on the temperature unit Kelvin as follows:

f=k·1.8–459.67

wherein k is an absolute temperature expressed in Kelvin and f is the same temperature in Fahrenheit. The following entity instances provide Fahrenheit as a unit:

IfcConversionBasedUnitWithOffset( IfcDimensionalExponents(0, 0, 0, 0, 1, 0, 0), THERMODYNAMICTEMPERATUREUNIT, ‘Fahrenheit’, IfcMeasureWithUnit( IfcThermodynamicTemperatureMeasure(1.8), IfcSiUnit(THERMODYNAMICTEMPERATUREUNIT, ?, KELVIN)), -459.67);
