This standard was last reviewed and confirmed in 2018. Therefore this version remains current.
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
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.
