Downloaded from https://www.everyspec.com APPENDIX C MIL-STD-31000A C.6 DETAILED REQUIREMENTS. C.6.1. Acceptance criteria. C.6.1.1. Geometric integrity. The Automotive Industry Action Group (AIAG) has defined a system for classifying and coding product data quality criteria. The codes allow criteria to be referenced in a consistent fashion in documents, databases and in computer applications that check 3D models. This guide employs a subset of the codes defined by the AIAG. Each code consists of three parts:
The domain identifier (a single-byte alphabetic character) - X The representation identifier (two alphabetic characters) - YY The parameter identifier (two alphabetic characters) – ZZ Example: A-YY-ZZ Permissible values for the domain identifier G Geometry-3D CAD model data O nOn-geometric data Proposed extensions A Annotation data Permissible values for the representation identifier CU CUrve ED EDge FA FAce LO edge LOop SH SHell SO SOlid model representation SU SUrface representation Proposed extensions AN Annotation element AS Assembly (top-level or subassembly) MO Model PT ParT in an assembly SV Saved View 68
