IfcObjectiveEnum

8.2.2.3 IfcObjectiveEnum

IfcObjectiveEnum is an enumeration used to determine the objective for which purpose the constraint needs to be satisfied.

HISTORY New enumeration in IFC2.0.

IFC4 CHANGE Extended to include CODEWAIVER.

Enumerated Item Definitions:

CODECOMPLIANCE: A constraint whose objective is to ensure satisfaction of a code compliance provision.
CODEWAIVER: A constraint whose objective is to identify an agreement that code compliance requirements (the waiver) will not be enforced.
DESIGNINTENT: A constraint whose objective is to ensure satisfaction of a design intent provision.
EXTERNAL: A constraint whose objective is to synchronize data with an external source such as a file.
HEALTHANDSAFETY: A constraint whose objective is to ensure satisfaction of a health and safety provision.
MERGECONFLICT: A constraint whose objective is to resolve a conflict such as merging data from multiple sources.
MODELVIEW: A constraint whose objective is to ensure data conforms to a model view definition.
PARAMETER: A constraint whose objective is to calculate a value based on other referenced values.
REQUIREMENT: A constraint whose objective is to ensure satisfaction of a project requirement provision.
SPECIFICATION: A constraint whose objective is to ensure satisfaction of a specification provision.
TRIGGERCONDITION: A constraint whose objective is to indicate a limiting value beyond which the condition of an object requires a particular form of attention.
