TS EN 9300-110

TS EN 9300-110 is a part of the LOTAR family for aerospace digital product documentation, focused on long-term archiving and retrieval of the explicit 3D geometry of single CAD parts. In practical terms, it addresses how a digital archive should preserve geometry so that the 3D information remains faithful to what the original CAD system produced, using an open data format.

What “explicit geometry information” means

In general technical usage, explicit geometry refers to the directly defined shapes in a CAD model: surfaces, edges, solids and their topological relations. This is different from the design intent or feature history that may exist inside a native CAD system. The distinction matters in aerospace because the geometric result is often the interoperable asset that must survive system changes, long retention periods and repeated reuse across digital workflows.

Archiving principles behind the standard

This part builds on the principles established in EN 9300-003, “Fundamentals and Concepts”, and frames archiving as more than file storage. The archive must support preservation of geometric integrity, future accessibility and consistent interpretation over time, which are central concerns when technical product data may need to be consulted decades after creation.

• Covers explicit 3D geometry for single CAD parts.
• Addresses long-term preservation and retrieval.
• Aims for lossless preservation relative to the original CAD output.
• Requires use of an open data format as part of the archiving approach.
• Relies on the foundational concepts of EN 9300-003.
