IfcPropertySingleValue Class
Syntax
C++
class IfcPropertySingleValue : public IfcSimpleProperty;

The property with a single value IfcPropertySingleValue defines a property object which has a single (numeric or descriptive) value assigned. It defines a property - single value combination for which the property Name, an optional Description, and an optional NominalValue with measure type is provided. In addition, the default unit as specified within the project unit context can be overridden by assigning an Unit. 

 

  • If the Unit attribute is not specified, than the unit is already implied by the type of IfcMeasureValue or IfcDerivedMeasureValue. The associated unit can be found at the IfcUnitAssignment globally defined at the project level (IfcProject.UnitsInContext).
  • If the Unit attribute is specified, the unit assigned by the Unit attribute overrides the globally assigned unit.
