What is an example of a tolerance that controls a feature's profile in both 2D and 3D?

Profile Tolerance is the correct answer because it specifically defines a tolerance zone that determines the allowable deviation of a feature's surface or contour from its ideal shape in both two-dimensional and three-dimensional contexts. This tolerance is essential for ensuring that complex shapes or contours maintain their intended design, accommodating both the flat and volumetric aspects of manufactured components.

In 2D, profile tolerance controls the shape of the feature on a plane, indicating how much it can deviate from the desired outline. In 3D, it allows for complex surfaces to remain within a defined tolerance volume around the intended profile, providing flexibility in manufacturing while ensuring that parts fit and function correctly in their final assembly.

The other options pertain to more specific aspects of geometric tolerancing. Form Tolerance relates to the shape of a feature alone, Orientation Tolerance deals primarily with the angular relationship of features, and Location Tolerance specifies the position of features relative to one another. While these tolerances are important, they do not address the overall profile control in the same comprehensive manner that Profile Tolerance does in both dimensions.
