5.4.3.53 IfcRelFillsElement
5.4.3.53.1 Semantic definition
IfcRelFillsElement is an objectified relationship between an opening element and an element that fills (or partially fills) the opening element. It is an one-to-one relationship.
As shown in Figure 5.4.3.53.A, the insertion of a door into a wall is represented by two separate relationships. First the door opening is created within the wall by IfcWall <-- IfcRelVoidsElement --> IfcOpeningElement, then the door is inserted within the opening by IfcOpeningElement <-- IfcRelFillsElement --> IfcDoor. The red mark in the figure indicates that there shall be no IfcRelContainedInSpatialStructure relationship that connects the opening to the spatial container of the wall.
