class Ifc4x1::IfcPointOnSurface : public Ifc4x1::IfcPoint

Definition from ISO/CD 10303-42:1992: A point on surface is a point which lies on a parametric surface. The point is determined by evaluating the surface at a particular pair of parameter values.

NOTE: Corresponding ISO 10303 entity: point_on_surface. Please refer to ISO/IS 10303-42:1994, p. 24 for the final definition of the formal standard.

HISTORY: New entity in Release IFC2x Edition 2.

Informal Propositions:

The parametric values specified for u and v shall not be outside the parametric range of the basis surface.
