# 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.
