A Point_direction_model is a model in three dimensional space consisting only of ordered sequences of points or of points with associated directions.
EXAMPLE For scanned data along planar intersections of a part, or for a model of an item, several point direction sequences can be used to specify the measured points together with the measured normal direction on the surface of the object in their sequence along the planar intersection. Another example is the specification of a tool path where the sequence specifies the tool path as a polygon and the direction specifies the direction of the tool, e.g., a miller, in each point of the path.
A Point_direction_model is a type of Geometric_model.
The data associated with a Point_direction_model are the following:
The point_direction_elements specifies the Point_direction_sequence elements of a Point_direction_model.
See point_direction_model to point_direction_sequence for the application assertion.
The point_elements specifies the Point_sequence elements of a Point_direction_model.
See point_direction_model to point_sequence for the application assertion.
