4.2.389 Point_direction_sequence

A Point_direction_sequence is an ordered list of points and of associated directions.

EXAMPLE A Point_direction_sequence may be used to represent the consecutive locations of a cutting tool during a machining operation.

A Point_direction_sequence is a type of Detailed_geometric_model_element.

The data associated with a Point_direction_sequence are the following:

element

The element specifies the Point_direction objects or the Point_on_surface objects that define the consecutive points and the appropriate axis directions. In the case of a Point_on_surface, the direction is the cross product of the principal tangent vectors u and v of the surface in this point.

See point_direction_sequence to point_direction and point_direction_sequence to point_on_surface for the application assertions.

There shall be at least one object that defines the element for a Point_direction_sequence.
