Function rectangular_trimmed_surface 

pub fn rectangular_trimmed_surface(
    tx: &mut Transaction,
    basis: EntityId,
    u: (f64, f64),
    v: (f64, f64),
) -> Result<EntityId, GeometryError>

Stage an IfcRectangularTrimmedSurface.

The senses are derived from the parameters, not taken from the caller: the schema requires Vsense = (V2 > V1) (and the same for u on most basis surfaces), so accepting a sense that could disagree would only create a way to write an invalid file.

Errors

Refuses u1 == u2 or v1 == v2 – a trim of zero extent in either direction – or a non-finite parameter.
