Hole/slot diameter ≥ material thickness |
SM-004 |
C_SHEET |
major |
Hole-to-edge distance: enforce guideline thresholds (distortion risk) |

Hem design: check minimum inside diameter and return length vs thickness |
SM-013 |
C_SHEET |
major |
Offset features: flag very small offsets likely to be inconsistent |
SM-014 |
C_SHEET |
