What is the term for the measurement of the dimensions of physical objects in drawings?

Dimensioning is the process that specifically refers to the measurement of the dimensions of physical objects as represented in technical drawings. It involves adding numerical values to the drawings to indicate size, location, and other attributes of the features they represent. This practice is essential in ensuring that each component is accurately represented and can be manufactured or constructed according to specified measurements.

Blueprinting commonly relates to the process of producing copies of technical drawings, often using a specific printing technique that creates blue and white images. While closely associated with dimensioning, it does not itself involve the measurement aspect.

Drafting is the broader skill of creating detailed drawings and plans, which may include dimensioning as part of the process but doesn't focus exclusively on measurements.

Designing refers to the conceptual and creative process of developing ideas and solutions, which may encompass many disciplines, including architecture and engineering, but does not specifically relate to the act of measuring dimensions in drawings.

Thus, dimensioning is the precise term that captures the act of measuring and marking dimensions in the context of physical object representation in technical drawings.
