Aerospace series. LOTAR. LOng Term Archiving and Retrieval of digital technical product documentation such as 3D, CAD and PDM data - Explicit CAD assembly structure Ingestion-build-111333 The BS 7121 series is1 Scope EN 9300115 describes the requirements, and particularly the information required, for the long term archiving and retrieval of a mechanical CAD explicit assembly structure. This will allow the retrieval of the assembly structure including the placement information. Figure 1 Assembly structure and geometric model The CAD assembly structure defines the collection of CAD parts into assemblies, and assemblies into higher level assemblies. An
