Entity definition

The IfcPresentationStyle is an abstract generalization of style table for presentation information assigned to geometric representation items. It includes styles for curves, areas, surfaces, and text. Style information may include colour, hatching, rendering, and text fonts.

The different styles may include length measures (directly as a length measure with infered unit, or indirectly as a ratio in relation to another length measure). They may apply to curve pattern, hatch line distances, text spacing and font sizes. The attribute ModelOrDraughting determines whether those length measures are provided as model or draughting measures.

Each subtype of  IfcPresentationStyle is assigned to the IfcGeometricRepresentationItem's through an intermediate IfcStyledItem.
