Aerospace series - LOTAR LOng-Term Archiving and Retrieval of digital technical product documentation such as 3D, CAD and PDM data - Part 100: Common concepts for long-term archiving and retrieval of 3D mechanical CAD information

Edition date: 2026-04-01
In Force
Available languages: English
Summary: This document specifies common fundamental concepts for long term archiving and retrieval of mechanical CAD information for elementary parts and assemblies. It details the “fundamentals and concepts” of EN 9300-003:2012 in the specific context of long-term archiving of CAD mechanical models. Mechanical CAD information is divided into assembly structure and geometrical information, both including explicit and implicit geometrical representation, geometric dimensioning and tolerancing with form features. The EN 9300-1XX series is organized as a sequence of parts, each building on the previous ones in a consistent way, each adding a level of complexity in the CAD data model. This includes the detailing of relationships between the essential information for the different types of CAD information covered by the EN 9300-1XX series. As technology matures, additional parts will be released in order to support new requirements within the aerospace community. 1.2 In Scope This document specifies: - the fundamentals and concepts for long-term archiving and retrieval of 3D mechanical CAD information; - the document structure of the EN 9300-1XX series, and the links between all these parts; - the qualification methods for long-term preservation of archived mechanical CAD information; more specially, principles for the CAD validation properties and for verification of the quality of the CAD archived file; - specifications for the preservation planning of archived CAD information; - specific functions for administration and monitoring of CAD archived mechanical models; - the definition of archive information packages for CAD data. 1.3 Out of scope The following are out of scope for this part: - long-term archiving of CAD 2D drawings; - other CAD specialization disciplines, such as electrical harnesses, composite.

1.1 Introduction Le présent document spécifie les concepts fondamentaux communs pour l'archivage à long terme et la récupération des données de CAO mécanique des pièces élémentaires et des assemblages. Il détaille les « fondamentaux et concepts » de l’EN 9300 003:2012 dans le contexte spécifique de l’archivage long terme des modèles de CAO mécanique. Les données de CAO mécanique sont divisées entre les données de structure d’assemblage et les données géométriques, et incluent la représentation géométrique explicite et implicite, le dimensionnement et tolérancement géométriques avec caractéristiques de forme. La série EN 9300 1XX est organisée en différentes parties, chacune se basant sur la précédente de façon cohérente, et chacune ajoutant un niveau de complexité au modèle de données CAO. Elle comprend le détail des relations entre les données essentielles pour les différents types de données de CAO couverts par la série EN 9300 1XX. À mesure de l’évolution technologique, des parties supplémentaires seront publiées afin de répondre aux nouvelles exigences au sein de la communauté aérospatiale. 1.2 Dans le domaine d'application Le présent document spécifie : — les fondamentaux et concepts pour l'archivage long terme et la récupération des données de CAO mécanique 3D ; — la structure des documents de la série EN 9300 1XX et les liens entre toutes ces parties ; — les méthodes de qualification pour la pérennisation des données de CAO mécanique archivées ; plus particulièrement, les principes pour les propriétés de validation CAO et pour la vérification de la qualité du fichier CAO archivé ; — les spécifications pour la planification de la pérennisation des données de CAO archivées ; — les fonctions spécifiques pour l’administration et la surveillance des modèles de CAO mécanique archivés ; — la définition des paquets d’informations archivées pour les données de CAO. 1.3 Hors domaine d'application La présente partie ne traite pas les points suivants : — l’archivage long terme des dessins CAO 2D ; — les autres disciplines de spécialisation en CAO, telles que les faisceaux électriques, les composites.
