8.12.3.16 IfcFillAreaStyleTiles

8.12.3.16.1 Semantic definition

The IfcFillAreaStyleTiles defines the filling of an IfcAnnotationFillArea by recurring patterns of styled two dimensional geometry, called a tile. The recurrence pattern is determined by two vectors, that multiply the tile in regular form.

The two vectors act as a two dimensional repeat factor that determines eight new positions for the tiles.

# Attribute Type Description
IfcRepresentationItem (2)
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.

IfcFillAreaStyleTiles (3)
1 TilingPattern LIST [2:2] OF IfcVector

A two direction repeat factor defining the shape and relative positioning of the tiles.

2 Tiles SET [1:?] OF IfcStyledItem

A set of constituents of the tile being a styled item that is used as the annotation symbol for tiling the filled area.

3 TilingScale IfcPositiveRatioMeasure

The scale factor applied to each tile as it is placed in the annotation fill area.
