Enum VectorOrDirection 

pub enum VectorOrDirection {
    Direction(EntityId),
    Vector(EntityId),
}

IfcVectorOrDirection = IfcDirection | IfcVector.

A vector carries a magnitude, a direction does not. Collapsing the two loses the length of an extrusion whose direction is given as a vector.

Variants

Direction(EntityId)

IfcDirection: orientation only.

Vector(EntityId)

IfcVector: orientation plus magnitude.
