14、 bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organiza
15、tions, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in t
16、he ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that
17、 some of the elements of this part of ISO 10303 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

24、 e This part of ISO 10303 species the interpretation of the generic resources for the denition of an ele mentary boundary representation model. The following are within the scope of this part of ISO 10303: the denition of an elementary_brep_shape_representation, this is a representation composed of
25、one or more manifold_solid_breps each of which is dened with elementary geometry and complete explicit topology; the denition of the unbounded geometry of curves and surfaces used in the denition of the faces of such a Brep model; the denition of the topological structure of a Brep model; 3D geometr
26、y; Breps; elementary curves, these are linesorconics; elementary_surfaces; geometric transformations; polylines; unbounded geometry; use of topology to bound geometric entities. The following are outside the scope of this part of ISO 10303: 2D geometry; bounded curves other than polylines; bounded s
27、urfaces; c ISO 2000 All rights reserved 1ISO 10303513:2000(E) offset curves and surfaces. This AIC is independent of any industrial application domain. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this par

40、he integrated resources and con tains the types, entity specializations, and functions that are specic to this part of ISO 10303. NOTE 1 There may be subtypes and items of select lists that appear in the integrated resources that are not imported into the AIC. Constructs are eliminated from the subt
41、ype tree or select list through the use of the implicit interface rules of ISO 1030311. References to eliminated constructs are outside the scope of the AIC. In some cases, all items of the select list are eliminated. Because AICs are intended to be implemented in the context of an application proto
42、col, the items of the select list will be dened by the scope of the application protocol. This application interpreted construct provides a consistent set of geometric and topological entities for the denition of manifold solid models with faces having elementary geometry and explicitly dened edges
43、and vertices. The faces of the Brep models are bounded by polylines, lines or conics. 4 c ISO 2000 All rights reservedISO 10303513:2000(E) The highest level entity in this AIC is the elementary_brep_shape_representation.
