Downloaded from https://www.everyspec.com APPENDIX C MIL-STD-31000A C.9.3 Model geometry validation criteria C.9.3.1 Different Model Area (G-MO-DS) Definition: The total surface area of all faces (solid, open shell and unsewn) in a translated model is different from the total surface area of all faces in the native model. Measurement: The percent change from the area of the native faces to the area of the translated faces. Effects of condition on model-based definition translation: This high-level criterion indicates a significant shape change. C.9.3.2 Different Model Location (G-MO-DL) Definition:
The centroid of all translated solids is different from the centroid of all solids in the native model. Measurement: The distance between the centroid of the native model to the centroid of the translated model divided by the diagonal distance across the bounding box of the native model. Effects of condition on model-based definition translation: This high-level criterion indicates a significant shape change. C.9.3.3 Different Model Volume (G-MO-DE) Definition: The total volume of all translated solids is different from the total volume of all solids in the native model. Measurement: The percent change from the volume of the native model to the volume of the translated model.
Effects of condition on model-based definition translation: This high-level criterion indicates a significant shape change. 142
