Orientation tolerances, when applied to plane surfaces, control flatness if a flatness tolerance is not specified.

Orientation Tolerances

Limitations placed on the angle or alignment of a feature in a technical drawing, ensuring it fits or functions as intended.

Plane Surfaces

Flat, two-dimensional surfaces extending infinitely in all directions within their plane.

Flatness

The condition of a surface having minimal curvature or deviation from being perfectly flat.

  • Understand the significance of form and orientation tolerances in defining geometric controls.
  • Understand the links and divergences between orientation tolerances and how they affect feature control.

Final Answer :
True
Explanation :
This statement is true. Orientation tolerances, such as parallelism or perpendicularity, can be used to control the flatness of a plane surface if a specific flatness tolerance is not specified. This is because if the orientation tolerances are within specification, it ensures that the surface is flat within a certain tolerance zone.
