This part of ISO 10303 specifies resource constructs for representing the complex shape elements, sometimesknown as form features, that are supported by the solid modelling capabilities of modern CADsystems. The elements are defined in such a way as to facilitate the exchange of solid models of productsrepresented in terms of their constructional history.NOTE 1 Procedural or constructional history models of solids can also include operations based directly onentities defined in ISO 10303-42, in particular Boolean operations and operations based on the various subtypes ofswept face solid and swept area solid.The following are within the scope of this part of ISO 10303:— the representation of solids having shape configurations resulting from blending and chamferingoperations;— the representation of solids with shape configurations resulting from offsetting, thickening, shellingand sculpturing operations;— the representation of solids having shape configurations characteristic of certain manufacturing features,including several types of holes, pockets, slots and grooves;— the representation of solids having circular and rectangular patterns of the types of shape configurationsmentioned in the previous item of this list;— the representation of solids that are generalizations of the solids of extrusion and revolution definedin ISO 10303-42.The following are outside the scope of this part of ISO 10303:— the representation of shape configurations on a model as aspects of the shape of the model, in thesense defined by ISO 10303-41;NOTE 2 For design purposes the configurations specified in this part of ISO 10303 are regarded as shape elementsin their own right, and not as local aspects of more complex shapes. These configurations can be created,subjected to modification and even subsequently deleted during the design process, so that they do not in generalappear in their original form as shape aspects of the final model.— the representation of features relating to manufacturing or other applications downstream of design.NOTE 3 Such features have associated semantics that are absent from the shape configurations defined in thispart of ISO 10303, which are purely concerned with the form of the modelled object.
