class Ifc4x2::IfcQuantityWeight : public Ifc4x2::IfcPhysicalSimpleQuantity

IfcQuantityWeight is a physical element quantity that defines a derived weight measure to provide an element’s physical property. It is normally derived from the physical properties of the element under the specific measure rules given by a method of measurement.

EXAMPLE The amount of reinforcement used within a building element may be measured according to its weight. The actual size of the weight depends on the method of measurement used.

HISTORY New entity in IFC2x. It replaces the calcXxx attributes used in previous IFC Releases.

Public Types

Public Functions

double WeightValue() const

Mass measure value of this quantity.

void setWeightValue(double v)
bool hasFormula() const

Whether the optional attribute Formula is defined for this IfcQuantityWeight.

std::string Formula() const

A formula by which the quantity has been calculated. It can be assigned in addition to the actual value of the quantity. Formulas could be mathematic calculations (like width x height), database links, or a combination. The formula is for informational purposes only.
