Which of the following describes numerical values relating to the size, location, or surface texture of a part?

The term that best describes numerical values relating to the size, location, or surface texture of a part is dimensions. In the context of welding and fabrication, dimensions provide precise measurements that detail the geometric features of a part, indicating how large or small it should be, as well as specifying where certain features should be located on that part.

Dimensions are often provided in drawings using a standardized form to ensure clarity and consistency in manufacturing. They can include linear measurements (length, width, height), angular measurements (degrees), and tolerances that specify permissible variations from these exact values.

While measurements generally refer to the act of determining the size or extent of something, they do not encompass the complete set of information provided in a technical drawing. Specifications can include a broader range of details like materials and processes, and indicators typically refer to marks or symbols that guide operators but do not convey exact numerical values related to the part's geometry. Therefore, dimensions are the most accurate term for these specific numerical representations.
