In scope
This document is applicable to:
- machine-interpretabl
- the association of the above with 3D geometric shapes;
- the possible association of the above with Presentation of 3D Product and Manufacturing Information (PMI), and 3D annotations as specified in EN 9300-120.
In EN 9300-121, the technology used to preserve this 3D information is based on semantic representation. The main use cases are Certification, Product Liability and Design re-use.
For the purpose of this document, the semantic definition is at the level that supports associative "Cross-highlighting"
Out of scope
This document is applicable to:
- PMI presentation (specified in EN 9300-120);
- User defined attributes that are assigned to 3D geometric entities or at the part level. The archiving of the UDA is specified in EN 9300-120.
- How to preserve additional information:
- property rights;
- form features;
- CAD Assemblies.
- The semantics of special Notes outside the scope of PMI: ITAR/EAR, proprietary, and title block information, etc.
