Aerospace series - LOTAR - Long Term Archiving and Retrieval of digital technical product documentation such as 3D CAD and PDM data - Part 110: CAD mechanical 3D Explicit geometry information
Abstract
The following is in scope of this document: — business specification for long term archiving and retrieval of CAD 3D explicit geometry (see Clause 5); — essential information of CAD 3D explicit geometry (solids, curves, surfaces, and points) to be preserved (see Clause 6); — data structures detailing the main fundamentals and concepts of CAD 3D explicit geometry (see Clause 7); — verification rules to check CAD 3D explicit geometry for consistency and data quality (see Clause 8); — validation rules to be stored with the CAD 3D explicit geometry in the archive to check essential characteristics after retrieval (see Clause 9). NOTE 1 This document includes the geometrical external shape resulting from CAD 3D domain elements (e.g., 3D Structural components, 3D Tubing, 3D electrical harness, 3D composite, etc.). The following is outside the scope of this document: — the formal definition of validation and verification rules to check 3D explicit geometry for consistency and data quality using a machine-readable syntax; — implicit or parametric geometry; — Geometric Dimensioning & Tolerancing (GD&T), Product & Manufacturing Information (PMI); NOTE 2 For long term archiving of the GD&T and PMI refer to EN 9300-120, EN 9300-121 and EN 9300-125. — assembly structures and PDM product structures; NOTE 3 For long term archiving of assembly structure refer to EN 9300-115 and for product structure refer to EN 9300-2xx series. — model styling and organization of explicit geometry.
