Downloaded from https://www.everyspec.com APPENDIX C MIL-STD-31000A C.7.3.2. Fragmented Edge (G-ED-FG). Definition: The number of segments in an edge curve exceeds the allowable maximum. Effects of condition on CAD data quality: Design and drafting: Tiny or discontinuous surface entities may be created. May impede changing geometry. Data exchange: Applications with restrictions on the number of segments may not be able to process data. Finite element analysis: Excessive small elements may be generated. Numerically controlled manufacturing: Tool paths may fail. Poor surface quality may be apparent in work pieces. Recommended correction:
Approximate the fragmented edge within acceptable tolerances by a curve with fewer segments. Delete the fragmented edge. C.7.3.3. Inconsistent edge on curve (G-ED-IO). Definition: The direction of an edge curve in parameter space is inconsistent with its underlying curve in 3D space. The criterion is true if the directions are consistent. Effects of condition on CAD data quality: Design and drafting: No effect on quality. Data exchange: Faces may not trim properly following translation. Finite element analysis: No effect on FE applications. Numerically controlled manufacturing: No effect. 103
