Aerospace series - LOTAR - LOng Term Archiving and Retrieval of digital technical product documentation such as 3D CAD and PDM data - Part 120: CAD 3D explicit geometry with graphic product and manufacturing information (Edition P 1)
"Introduction This document defines the requirements for the long term digital preservation of the presentation of Product and Manufacturing Information (PMI) with their possible links to the 3D explicit shape and geometry of single CAD parts. The goal is to preserve this 3D information with respect to the geometry and related PMI produced by the original CAD system@ following the principles laid down in EN 9300-003 ??Fundamentals and Concepts??. The requirements of EN 9300-110 ??CAD mechanical 3D explicit geometry information?? about the preservation of the 3D explicit shape shall apply within this document. The meaning of terms ""Presentation"" and ""Representation""@ defined in the EN 9300-100 ??Common concepts for Long term archiving and retrieval of CAD 3D mechanical information?? is required to understand this EN 9300 document."
