GB/T 16656.501-2005 Industrial automation systems and integration.Product data representation and exchange.Part 501:Application interpreted construct:Edge-based wireframe (English Version)
This part of GB/T 16656 specifies the interpretation of integrated resources to meet the need to express the shape of a product using a three-dimensional wireframe model whose boundaries are formed by a collection of connected edges. This standard applies to: - the representation of a wireframe model is described by edges and vertices, and the edges intersect only at their vertices; - the wireframe model is expressed by one or more connected edge sets, and the edge sets cannot intersections other than edges; —points defined in a three-dimensional coordinate space; —curves defined in a three-dimensional coordinate space, including B-spline curves; —expression of a single wireframe model or a combination of wireframe models. This standard does not apply to: - geometry defined in two-dimensional coordinate space; - surface geometry; - solid geometry; - shell topology.
