| IfcInclinedReferenceSweptAreaSolid | ADDED |
An IfcInclinedReferenceSweptAreaSolid is a specialized IfcDirectrixDistanceSweptAreaSolid. The orientation of the profile's x-axis is always follows the rule defined by the IfcAxisLateralInclination.
| # | Attribute | Type | Cardinality | Description | G |
|---|---|---|---|---|---|
| 6 | FixedAxisVertical | IfcBoolean | ? | Indicates whether the profile is oriented with its Y axis facing upwards in +Z direction (True), or vertically perpendicular to the Directrix varying according to slope (False). | X |
| 7 | Inclinating | IfcAxisLateralInclination | The lateral inclination profile which defines the rule for the orientation of the x-axis of the profile in sweeping operation. | X |

| IfcRepresentationItem | |||||
| LayerAssignment | IfcPresentationLayerAssignment @AssignedItems | S[0:1] | Assignment of the representation item to a single or multiple layer(s). The LayerAssignments can override a LayerAssignments of the IfcRepresentation it is used within the list of Items.
IFC2x3 CHANGE The inverse attribute LayerAssignments has been added. IFC4 CHANGE The inverse attribute LayerAssignment has been restricted to max 1. Upward compatibility for file based exchange is guaranteed. | X | |
| StyledByItem | IfcStyledItem @Item | S[0:1] | Reference to the IfcStyledItem that provides presentation information to the representation, e.g. a curve style, including colour and thickness to a geometric curve.
IFC2x3 CHANGE The inverse attribute StyledByItem has been added. | X | |
| IfcGeometricRepresentationItem | |||||
| IfcSolidModel | |||||
| Dim :=3 | IfcDimensionCount | The space dimensionality of this class, it is always 3. | X | ||
| IfcSweptAreaSolid | |||||
| 1 | SweptArea | IfcProfileDef | The surface defining the area to be swept. It is given as a profile definition within the xy plane of the position coordinate system. | X | |
| 2 | Position | IfcAxis2Placement3D | ? |
Position coordinate system for the resulting swept solid of the sweeping operation. The position coordinate system allows for re-positioning of the swept solid. If not provided, the swept solid remains within the position as determined by the cross section or by the directrix used for the sweeping operation.
IFC4 CHANGE The attribute has been changed to OPTIONAL with upward compatibility for file-based exchange. | X |
| IfcDirectrixDistanceSweptAreaSolid | |||||
| 3 | Directrix | IfcCurve | The curve used to define the sweeping operation. The solid is generated by sweeping the SELF\IfcSweptAreaSolid.SweptArea along the Directrix. | X | |
| 4 | StartDistance | IfcDistanceExpression | ? | Distance expressions indicating the position where the sweeping operation starts along the Directrix. If no distance expression provided the start of the sweeping operation is at the start of the Directrix. | X |
| 5 | EndDistance | IfcDistanceExpression | ? | Distance expressions indicating the position where the sweeping operation ends along the Directrix. If no distance expression provided the end of the sweeping operation is at the end of the Directrix. | X |
