Part 502:
Application interpreted construct: Shell-based wireframe
1 Scope
This part of ISO 10303 specifies the interpretation of the integrated resources to satisfy requirements for the
representation of the product shape using three-dimensional wireframe models which are bounded by a set
of shells.
The following are within the scope of this part of ISO 10303:
— the representation of wireframe models that are described by a graph of edges and vertices where the
edges intersect only at their vertices;
— the representation of a wireframe model by one or more shells that shall not overlap or intersect except
at their vertices or edges;
— points defined in a three-dimensional coordinate space;
— curves, including b-splines, defined in a three-dimensional coordinate space;
— the representation of a single wireframe model or an assembly of wireframe models.
The following are outside the scope of this part of ISO 10303:
— geometry defined in a two-dimensional coordinate space;
— surface geometry;
— solid geometry;
— references to eliminated constructs.

4.1 Introduction
This part of ISO 10303 provides the geometric and topological structures to represent three dimensional
shapes using shells of dimensionality 0 (vertex_shell) or 1 (wire_shell). This AIC is represented by the
entity shell_based_wireframe_shape_representation, that is a shape_representation
4.2 Fundamental concepts and assumptions
The wireframe representation of shapes is based on the shell_based_wireframe_model and the geometric
and topological entities required. The shapes represented by the shell_based_wireframe_shape_-
representation are those whose definition can be satisfied by collections of vertex_shells or wire_shells.
Wireframe representations may be assemblies of other wireframe representations that are mapped to the
same coordinate space.
4.3 aic_shell_based_wireframe entity definition: shell_based_wireframe_-
shape_representation
A shell_based_wireframe_shape_representation is a three-dimensional shape_representation that
represents the shape or a portion of the shape of a product by wireframes that define an implicit volume.
This includes all three-dimensional curves and topological entities that define a graph of vertices, edges, and
loops.
shape_representation
NOTE - An application protocol that uses this AIC may ensure that the entity is instantiated as a
shell_based_wireframe_shape_representation.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
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 organizations, 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.
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.
International Standard ISO 10303-501 was prepared by Technical Committee ISO/TC 184, Industrial
automation systems and integration, Subcommittee SC4, Industrial data.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
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 organizations, 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.
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.
International Standard ISO 10303-501 was prepared by Technical Committee ISO/TC 184, Industrial
automation systems and integration, Subcommittee SC4, Industrial data.
