Which annotation would you select to label a hole in a drawing?

To label a hole in a drawing, using a hole callout is the most appropriate choice. A hole callout provides specific details about the hole, such as its diameter, depth, and any threading if applicable. This type of annotation consolidates relevant information in a concise manner, making it clear to anyone reading the drawing what the specifications of the hole are.

A hole callout automatically pulls data from the hole feature in the 3D model, ensuring that the dimensions and characteristics are accurate and reflect any design changes. This integration streamlines the documentation process and enhances clarity in technical communication, which is crucial in engineering and manufacturing settings.

In contrast to this, while dimensions can denote measurements, they do not inherently convey specific information about hole features like a hole callout does. A text box offers flexibility for custom notes but lacks the structured, standardized information provided by a callout. Lastly, a hole feature itself refers to the underlying design element in the 3D model rather than the annotation needed on a 2D drawing. Therefore, a hole callout uniquely serves the purpose of labeling holes effectively in technical drawings.
