4.2.343 Offset_curve

An Offset_curve is a curve in 2D or 3D space that is defined as a set of points for which there is at least one point on the basis curve that is at the offset distance of the considered point. At a given point of the basis curve, the distance is measured along a vector that is the normalized cross product of the tangent of the basis curve at this point, and of a reference direction vector.

The reference direction of the offset shall be defined. An Offset_curve shall not self-intersect and may reference any type of curve except another Offset_curve.

An Offset_curve is a type of Curve.
