Industrial automation systems and integration — Product data representation and exchange — Part 501: Application interpreted construct: Edge based wireframe

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 that are bounded by a set of connected edge sets. 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 connected edge sets 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; — shell topology.

4.1 Introduction
This part of ISO 10303 provides geometric, topological, and wireframe entities for the representation of a
shape that consists of points and curves, with the topological structures providing connectivity. This AIC is
represented by the entity edge_based_wireframe_shape_representation, that is a shape_representation
(see ISO 10303-41).
4.2 Fundamental concepts and assumptions
This wireframe representation of a shape is based on the edge_based_wireframe_model and the geometric
and topological entities required.  The shapes represented by the edge_based_wireframe_shape_-
representation are those with definitions that only require collections of edges.  Wireframe representations
may be assemblies of other wireframe representations that are mapped to the same coordinate space.
4.3 aic_edge_based_wireframe entity definition: edge_based_wireframe_-
shape_representation
An edge_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 are trimmed by edge
topology. This includes all three-dimensional curves and topological entities that define a graph of vertices
and edges.
NOTE - An application protocol that uses this AIC may ensure that the shape_representation entity is
instantiated as an edge_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.
