IFC Assignments

IFC Group (IfcGroup): Use this to group any project elements (building element, story etc.) together. For example: the column and beam components of a frame standing are grouped together. Grouping by multilevel-hierarchy is also available for IfcGroup assignments. For example, you can group the frame standing groups in a ‘frame-system’ group.
IFC Zone (IfcZone): Use this to group IfcSpace elements (the equivalent of ARCHICAD Zones) together. For example: ARCHICAD Zones having the identical function are grouped into an IfcZone named e.g. “Security Zone.” Grouping by multilevel-hierarchy is also available for IfcZone assignments. For example, you can group some ARCHICAD Zones (IfcSpaces) in an IfcZone (Security Zones) that is a part of a higher level IfcZone group (Governmental Zones).
IFC System (IfcSystem): Use this to group any project elements (especially MEP elements) in a system hierarchy manually, by using MEP Modeler defined systems, or by importing systems exported from e.g. MEP applications. Definition of sub-system hierarchy (parent and child system) is also available. For example: group elevators in a vertical circulation system which can be a child system of a mechanical system. Or, assign plumbing elements to the cold water sub-system of a plumbing system. You can also tie systems to a spacial structure relation (IfcSite, IfcBuilding, IfcStorey or IfcSpace). For example, add to a duct system all the ARCHICAD Zones (IfcSpace) that it runs through.
Actor (IfcActor): Use this to assign an actor (person and/or organization) and its role (e.g. owner, architect, client) to any project element (project, story, building element etc.). Example: assign the Actors “Project Architect” and “Project Client/Owner” (GSA requirements) to the (Ifc)Project.
Space Occupant (IfcOccupant): Use this to define the occupancy relationship between an actor (person and/or organization) and one or more IfcSpaces or their groups (IfcZone).
Time Series Schedule (IfcTimeSeriesSchedule): Use this to set occupancy, lighting and equipment schedule assignment to any project element such as an ARCHICAD Zone. For example: issues (values) can be assigned to IfcSpaces with definite start and end dates, time steps, and annual, monthly, weekly, daily or custom repeating periods.
