Summary
Location controls define where features must be relative to datums.
Scope
Use location controls to establish true position or coaxiality relative to a datum reference frame.
Controls in this category
- GDT:Position
- GDT:Position Composite FCF
- GDT:Position Multi-Single Segment FCF
- GDT:Concentricity
- GDT:Symmetry
When to use it
Use location controls when the feature location drives fit, assembly, or function.
Common mistakes
- Missing basic dimensions for true position.
- Omitting datum references.
- Mixing location and orientation controls without clear intent.
