Use Definitions

IfcCondition is a particular subtype of IfcGroup that can contain only instances of IfcConditionCriterion. The objectified relationship class IfcRelAssignsToGroup is used to assign the related instances of IfcConditionCriterion to the relating instance of IfcCondition.

An IfcCondition is determined either from an observed or a measured state (see IfcConditionCriterion). The condition is determined at a particular point in time, the time being determined through the IfcRelAssociatesDateTime class with an appropriate designation for the value of the DateTimeType e.g. AssessmentDate. Note that other dates may be assigned to IfcCondition for relevant purposes e.g. to recommend the date for the next condition assessment.

IfcRelAssignsToProduct is used to relate one or more instances of IfcCondition to an artefact that is an instance of a subtype of IfcProduct. For an instance of IfcAsset, condition is related through the use of IfcRelAssignsToGroup.
