Downloaded from https://www.everyspec.com APPENDIX C MIL-STD-31000A C.9.4.8 Different Part Location (G-PT-DL) Definition: The centroid of a translated part is different from the centroid of the matching part in the native model. Measurement: The distance between the centroid of the native part to the centroid of the translated part divided by the diagonal distance across the bounding box of the native part. Effects of condition on model-based definition translation: This high-level criterion indicates a significant change in the position and/or orientation of the part. C.9.5 3D Annotation validation criteria C.9.5.1 Unmatched Annotation (A-AN-UM) Definition:
An annotation in one model has no corresponding annotation in the other model. Measurement: The criterion is false if any annotation in the native model does not have a matching annotation in the translated model. Effects of condition on model-based definition translation: If the unmatched annotation is in the native model, it represents significant data loss. If it is in the translated model, it likely indicates incorrect filtering during translation and will cause confusion. C.9.5.2 Split Annotations (A-AN-SP) Definition: An annotation in the native model corresponds to two or more annotations in the translated model. Measurement:
The criterion is false if any occurrences of this condition exist in the model pair. Effects of condition on model-based definition translation: Causes confusion if the derivative model is intended to only preserve visual presentation. If a semantic representation derivative is intended, this can cause the native annotation parameters to be lost. C.9.5.3 Merged Annotation (A-AN-MR) Definition: An annotation in the translated model corresponds to two or more annotations in the native model. Measurement: The criterion is false if any occurrences of this condition exist in the model pair. 145
