The cylindrical surface is a surface unbounded in the direction of z. Bounded cylindrical surfaces are defined by using a subtype of IfcBoundedSurface with BasisSurface being a cylindrical surface.
The inherited attributes are interpreted as
- SELF\IfcElementarySurface.Position defines the location and orientation of the cylindrical surface.
- SELF\IfcElementarySurface.Position.Location defines a point on the axis of the cylindrical surface.
- SELF\IfcElementarySurface.Position.P defines the direction of the axis of the cylindrical surface.
|LayerAssignment||SET [0:1] OF IfcPresentationLayerAssignment FOR AssignedItems||
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.
|StyledByItem||SET [0:1] OF IfcStyledItem FOR Item||
Reference to the IfcStyledItem that provides presentation information to the representation, e.g. a curve style, including colour and thickness to a geometric curve.
This attribute is formally derived.
The space dimensionality of IfcSurface. It is always a three-dimensional geometric representation item.
The position and orientation of the surface. This attribute is used in the definition of the parameterization of the surface.
