ISO/TS 10303-1501:2004 (R2021)

ISO/TS 10303-1501:2004 specifies the application module Edge based wireframe. The following are within the scope of ISO/TS 10303-1501:2004: 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; the representation of points defined in a three-dimensional coordinate space; the representation of curves, including b-splines, defined in a three-dimensional coordinate space; the representation of a single wireframe model or an assembly of wireframe model.
