== Summary ==
Profile of a surface controls the 3D form of a surface relative to its true profile.

== Definition ==
The tolerance zone is a uniform boundary about the true profile surface. The entire surface must lie within this zone.

== When to use it ==
Use profile of a surface to control complex surfaces where both form and location must be managed together.

== Examples ==
{{GDT Example
|title=Surface profile with datums
|body=Profile of a surface applied to a contoured face located by basic dimensions and datums.
}}

== Common mistakes ==
* Not locating the true profile with basic or toleranced dimensions.
* Applying the profile to a datum surface in an ambiguous way.
* Using prohibited modifiers.
