class Ifc4x2::IfcPointOnCurve : public Ifc4x2::IfcPoint

Definition from ISO/CD 10303-42:1992: A point on curve is a point which lies on a curve. The point is determined by evaluating the curve at a specific parameter value. The coordinate space dimensionality of the point is that of the basis curve.

NOTE: Corresponding STEP entity: point_on_curve. Please refer to ISO/IS 10303-42:1994, p. 23 for the final definition of the formal standard.

HISTORY: New entity in Release IFC2x Edition 2.

Informal Propositions:

The value of the point parameter shall not be outside the parametric range of the curve.
