EN 9300-115:2018 (E) 3 European foreword This document (EN 9300-115:2018) has been prepared by the Aerospace and Defence Industries Association of Europe - Standardization (ASD-STAN). After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received the approval of the National Associations and the Official Services of the member countries of ASD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2019, and conflicting national standards shall be withdrawn at the latest by January 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 9300-115:2018

EN 9300-115:2018 (E) 4 Foreword This standard was prepared jointly by AIA, ASD-STAN, PDES Inc and the PROSTEP iViP Association. The PROSTEP iViP Association is an international non-profit association in Europe. For establishing leadership in IT-based engineering it offers a moderated platform to its nearly 200 members from leading industries, system vendors and research institutions. Its product and process data standardization activities at European and worldwide levels are well known and accepted. The PROSTEP iViP Association sees this standard and the related parts as a milestone of product data technology. PDES Inc is an international non-profit association in USA. The mission of PDES Inc is to accelerate the development and implementation of ISO 10303, enabling enterprise integration and PLM interoperability for member companies. PDES Inc gathers members from leading manufacturers, national government agencies, PLM vendors and research organizations. PDES Inc. supports this standard as an industry resource to sustain the interoperability of digital product information, ensuring and maintaining authentic longevity throughout their product lifecycle. Readers of this standard should note that all standards undergo periodic revisions and that any reference made herein to any other standard implies its latest edition, unless otherwise stated. The Standards will be published under two different standards organizations using different prefixes. ASD Stan will publish the standard under the number EN 9300–xxx. AIA will publish the standard under the number NAS 9300–xxx. The content in the EN 9300 and NAS 9300 documents will be the same. The differences will be noted in the reference documentation (i.e. for EN 9300 Geometric Dimensioning & Tolerancing will be referenced in ISO 1101 and ISO 16792, and for NAS 9300 the same information will be referenced in ASME Y14.5M and Y 14.41). The document formatting etc. will follow that of the respective editorial rules of ASD-Stan and AIA. SIST EN 9300-115:2018

EN 9300-115:2018 (E) 5 1 Scope EN 9300-115 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 assembly can contain several occurrences of the same part or subassembly. The assembly structure is a tree, in which the leaf nodes are individual parts, and the non-leaf nodes are assemblies. The parent/child relationship between two nodes records not only that the child is part of a higher assembly, but also the relative position of that child in that assembly. This standard covers the archiving of the tree structure and the associated positioning information. The geometry of the individual component parts is out of scope. The assembly structure can be recorded in the same file as the geometry, or can cite the geometry as an external reference. The assembly structure can be supplied as a single file, or as a set of files, with cross references between files.

Figure 2 — Example of the scope of the Part 115 NOTE 1 An assembly node may contain geometry that is defined directly in the coordinate system of the assembly rather than through a child node with a corresponding transformation matrix to move the part into the assembly co-ordinate system. Some modeling systems call this a hybrid assembly. This kind of assembly is within the general scope of this part; however no specific verification and validation rules for this geometry are defined. SIST EN 9300-115:2018

EN 9300-115:2018 (E) 6 Out of scope: — The archiving of the geometric model of the components; — The management of different occurrences of the same part that have different geometry; — The management of different occurrences of the same part that have different attributes; — The archiving of assembly-by-constraint (where, for example, the position of a part is given as “perpendicular to part X”, rather than given as a positioning matrix); — The archiving of the Geometrical Dimensioning and Tolerance (GD&T); — The archiving of assembly Form Features. NOTE 2 Product assembly structure may be defined based on the data base management system approach. This case uses other fundamental concepts not covered in this part. See family EN 9300-2xx. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

EN 9300-115:2018 (E) 7 5 Business specifications for the long term archiving and retrieval of the explicit CAD assembly structure 5.1 Use cases The following clauses record the potential use cases for the archiving of an explicit CAD assembly structure. “Annex A: Recommended archiving scenarios” identifies the main archiving scenarios corresponding to these two use cases. 5.1.1 UC1: Full archiving The term “full archiving” is used where the complete assembly structure is archived as a single unit, and all the assembly structure data are contained in the same Submission Information Package (SIP). The assembly may be contained in one file or in a set of files (see Figure 3: archiving overview of the submission information package).

Figure 3 — Archiving overview of the submission information package 5.1.2 UC2: Bottom up and incremental archiving The assembly structure is archived subset by subset. The assembly structure files are submitted in different submission information packages. For example, in bottom-up archiving, the assembly structure files are submitted from the lower level up to the top level (see Figure 4).

Figure 4 — Bottom up archiving of the assembly structure 6 Essential information for explicit CAD assembly structure The following list describes the essential information for a CAD assembly structure. The essential information are captured, verified and validated through the core model and the rules. The core model is described in the Clause 7 “Definition of Core Model for an explicit CAD assembly structure” and the rules are described in the Clause 8 “Verification rules of CAD explicit assembly structure” and Clause 9 “Validation rules off an explicit CAD assembly structure”.
