Note: There is a newer version of this specification see VEC 2.1.0

The Curve3D is an abstract representation of a curve, that defines the three-dimensional appearance of the centreline of a segment. The concrete type of the curve (e.g. NURBSCurve) defines the mathematical function that applies to curve and stores the required parameter set for this function in the VEC.
