This standard - ISO 16757 Part 2: Geometry - describes the modelling of BS product geometry. The description is optimized for the interchange of product catalogue data and includes - shapes for representing the product itself, - symbolic shapes for the visualisation of the product's function in schematic diagrams, - spaces for functional requirements, - surfaces for visualisation, and - ports to represent connectivity between different objects. The shape and space geometry is expressed as Constructive Solid Geometry (CSG) based on geometric primitives concatenated to boundary representations by Boolean operations. The standard uses the applicable primitives from ISO 10303-42 (STEP geometry) and from ISO 16739 (IFC) and adds primitives which are required for the special geometry of Building Services products. For symbolic shapes, line elements are also used. This standard neither describes the inner structure and internal functionality of the product nor the manufacturing information, because this is typically not published within a product catalogue. BS products can have millions of variant dimensions. The parametric model used will result in smaller data files, which can be simply transmitted during data exchanges. The geometry model used does not contain any drawing information such as views, line styles or hatching.
