This collection is a standard for the exchange of product model data (STEP) module and resource library (SMRL). It is intended for those who are considering adopting ISO 10303 modular application protocols, application modules, and resource parts, or systems built on them, for product data representation …
Abstract
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.
