Downloaded from https://www.everyspec.com APPENDIX C MIL-STD-31000A Feature-translation software reads the model from the originating 3D CAD system. Figure 33. The operator may choose to have the model translated as a boundary representation (b-rep), a fully featured model, or both (dual mode). The translator then matches, maps, recognizes, or decomposes the features of the originating system into features understood by the target system. Figure 34. List of features awaiting conversion. The operator chooses the acceptance criteria for a successful feature translation. If the criteria are not met, the part will be translated as b-rep only. 160
