Which of the following dimensions specifies the location of a hole in a part?

The correct choice is feature dimension, as this term specifically refers to the dimensions that are used to locate the features of a part, such as holes, slots, and other geometric elements. Feature dimensions provide precise measurements that indicate where these features should be positioned relative to other elements of the part. In the context of welding print reading, understanding feature dimensions is crucial because they ensure that components fit together correctly and perform their intended function.

General dimensions typically encompass broad measurements of the part itself and do not specifically indicate the locations of individual features like holes. Tolerance dimensions define the allowable variation for dimensions but do not convey specific locations of features. Overall dimensions provide the overall size and limits of a part but do not directly address the placement of individual features. Therefore, feature dimension is the most appropriate choice for specifying hole locations on a part.
