ISO 16757-2:2016 describes the modelling of building services product geometry. The description is optimized for the interchange of product catalogue data and includes<\/p>\n

– shapes for representing the product itself,<\/p>\n

– symbolic shapes for the visualization of the product's function in schematic diagrams,<\/p>\n

– spaces for functional requirements,<\/p>\n

– surfaces for visualization, and<\/p>\n

– ports to represent connectivity between different objects.<\/p>\n

The shape and space geometry is expressed as Constructive Solid Geometry (CSG) based on geometric primitives concatenated to boundary representations by Boolean operations. ISO 16757-2:2016 uses the applicable primitives from ISO 10303-42 and from ISO 16739 and adds primitives which are required for the special geometry of building services products. For symbolic shapes, line elements are also used.<\/p>\n

ISO 16757-2:2016 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.<\/p>\n

Building services products can have millions of variant dimensions. To avoid the exchange of millions of geometries, a parametric model is introduced which allows the derivation of variant-specific geometries from the generic model. This is necessary to reduce the data to be exchanged in a catalogue to a manageable size. The parametric model will result in smaller data files, which can be easier transmitted during data exchanges.<\/p>\n

The geometry model used does not contain any drawing information such as views, line styles or hatching.<\/p>\n","protected":false},"excerpt":{"rendered":"
