8.12.3.7 IfcCurveStyleFontAndScaling
8.12.3.7.1 Semantic definition
The IfcCurveStyleFontAndScaling allows for the reuse of the same curve style definition in several sizes. The definition of the CurveFontScale is the scaling of a base curve style pattern to be used as a new or derived curve style pattern.
The CurveFontScale should not be mixed up with the target plot scale.An example for IfcCurveStyleFontAndScaling is the sizing of a basic curve style dash pattern 'dash' (visible 0.01m, invisible 0.005m) into 'dash large' with CurveFontScale = 2 (resulting in visible 0.02m, invisible 0.01m), and into 'dash small' with CurveFontScale = 0.5 (resulting in visible 0.005m, invisible 0.0025m).
Definition according to ISO/CD 10303-46:1992 A curve style font and scaling is a curve style font and a scalar factor for that font, so that a given curve style font may be applied at various scales. Corresponding ISO 10303 name: curve_style_font_and_scaling. Please refer to ISO/IS 10303-46:1994 for the final definition of the formal standard. New entity in IFC2x2.8.12.3.7.2 Entity inheritance
