Enum CurveMeasure 

pub enum CurveMeasure {
    Length(f64),
    Parameter(f64),
}

A length along a curve, or a parameter in its own space.

IfcCurveMeasureSelect admits either, and the two are not interchangeable: a length is in the model’s length unit, a parameter is in whatever the curve’s own parameterisation uses. Writing one where the other is meant rescales the segment.

Variants

Length(f64)

IfcNonNegativeLengthMeasure: a distance along the curve.

Parameter(f64)

IfcParameterValue: a value in the curve’s parameter space.
