Detailed Description

The standard opening, IfcOpeningStandardCase, defines an opening with certain constraints for the dimension parameters, position within the voided element, and with certain constraints for the geometric representation. The IfcOpeningStandardCase handles all cases of openings, that:

are true openings where the opening depth is greater than or equal to the thickness of the element, and the PredefinedType is set correctly to .OPENING. are true recesses where the opening depth is lower than the thickness of the element, and the PredefinedType is set correctly to .RECESS. are extruded perpendicular to the wall plane in case of openings in a wall are extruded perpendicular to the slab plane in case of openings in a slab have a local placement relative to the local placement of the voided element have a 'Body' shape representation with 'SweptSolid' representation type have only a single extrusion body within the 'Body' shape representation

  • Placement - The following constraint is mandatory for IfcOpeningStandardCase: The PlacementRelTo relationship of IfcLocalPlacement should point to the local placement of the same element, which is voided by the opening, i.e. referred to by VoidsElement.RelatingBuildingElement.
  • Body Geometry - The geometric representation of IfcOpeningStandardCase is defined using the following multiple shape representations for its definition: Body: A SweptSolid representation defining the 3D subtraction shape of the standard opening
  • Body Representation - The body representation of IfcOpeningStandardCase is represented using the representation type 'SweptSolid'. The standard geometric representation of IfcOpeningStandardCase is defined using the 'SweptSolid' representation. The following attribute values for the IfcShapeRepresentation holding this geometric representation are be used: RepresentationIdentifier : 'Body' RepresentationType : 'SweptSolid'

The following additional constraints apply to the swept solid representation: Solid: a single IfcExtrudedAreaSolid is required Profile: IfcRectangleProfileDef, IfcCircleProfileDef and IfcArbitraryClosedProfileDef are supported. Extrusion: The profile is extruded horizontally (i.e. perpendicular to the extrusion direction of the voided element) for wall openings, or vertically (i.e. in the extrusion direction of the voided element), for slab openings.

As shown on the image below, the orientation of the opening profile that is extruded for the opening body guarantees the following interpretation of dimension parameter for rectangular openings: IfcRectangleProfileDef.YDim interpreted as opening width IfcRectangleProfileDef.XDim interpreted as opening height
