getProjectUnitConversionFactor

This function will return the conversion factor compared to the base SI unit. The possible unitType values are all enumeration values from enumeration type IfcUnitEnum. For example getProjectUnitConversionFactor(model, "LENGTHUNIT") returns 0.001 in case of MilliMeters. Optional arguments unitPrefix (for example "MILLI"), unitName (if defined) and SIUnitName (for example "METRE") can be requested.
