IfcWorkControl

IfcWorkControl

Definition from IAI: An IfcWorkControl is an abstract supertype that captures information which is common to both IfcWorkPlan and IfcWorkSchedule

A work control may have resources assigned to it, this is handled by the IfcRelAssignsToResources relationship. The assignment of tasks to the work control is handled by the IfcRelAssignsTasks relationship.

The inherited attributes have the following meaning:

IfcControl.Controls - included in the set are references to the IfcRelAssignsTasks, which assign IfcTask's including time schedule controls.

IfcObject.HasAssignments - included in the set are references to the IfcRelAssignsToResources, which assign an IfcResource to the IfcWorkControl.
