Redundant constraints — Reference record
Two contacts intended to locate the same direction can compete when the part or fixture varies. More contacts do not guarantee better repeatability.
| Reference record | Working notes |
|---|---|
| Overview | Redundant constraints |
| Practical example | Highlight contacts sharing a normal direction and describe whether each is locating, supporting or floating. |
| Limits and interpretation | Do not remove or relax a real constraint without an engineering review. |
