Summary
Profile controls define a tolerance zone around a true profile in 2D or 3D.
Scope
Use profile controls to manage both form and location of complex shapes, often with a single requirement.
Controls in this category
- GDT:Profile of a Line
- GDT:Profile of a Surface
- GDT:Profile Composite FCF
- GDT:Profile Multi-Single Segment FCF
When to use it
Use profile when you need an overall shape control that can also relate to datums.
Common mistakes
- Not locating the true profile with basic or toleranced dimensions.
- Applying profile to a datum surface in an ambiguous way.
- Using prohibited modifiers such as diameter or MMC/LMC where not allowed.
