A Product_point_space is a Product_feature_space that consists of a set of points within a Product_specification_or_set. These points can change their absolute and relative positions as the Product_specification_or_set moves or deforms.
NOTE - A three dimensional volume view of a structure is a Product_point_space. Each member of the space is a point within the volume.
The points are usually identified by their position within the structure, for a reference state of the structure.
