8.13.3.5 IfcTextLiteral
8.13.3.5.1 Semantic definition
The text literal is a geometric representation item which describes a text string using a string literal and additional position and path information. The text size and appearance is determined by the IfcTextStyle that is associated to the IfcTextLiteral through an IfcStyledItem.
The text string is placed within the planar extent (the box) defined within the subtype IfcTextLiteralWithExtent.
Entity adapted from text_literal defined in ISO10303-46 New entity in IFC2x2. The IfcTextLiteral has been changed by removing Font and Alignment.DEPRECATION The use of IfcTextLiteral is deprecated and it will be made abstract.

| # | 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. The inverse attribute LayerAssignments has been added. The inverse attribute LayerAssignment has been restricted to max 1. Upward compatibility for file based exchange is guaranteed. |
|
| 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. The inverse attribute StyledByItem has been added. |
