GB/T 16656.501-2005Industrial automation systems and integration -- Product data representation exchange -- Part 501: Application interpreted construct: Edge-based wireframe (English PDF)

What this standard covers

This standard specifies the integrated resources explanation to satisfy the expression products using 3D wireframe model of the shape of the demand, the three-dimensional wireframe model boundary constituted by a set of connected edges. This section applies to: wireframe model expression described by the edges and vertices, edges intersect only at its apex, wireframe model consists of one or more expressions connected set of edges, edge set can not overlap or intersect outside the vertex or edge, in three-dimensional coordinate space defined points, in three-dimensional coordinate space defined curves, including the B-spline curves, single wireframe model or a combination of wireframe model expression. This section does not apply to: a two-dimensional coordinate space defined geometry, surface geometry, solid geometry, shell topology.
