Zeichnungsmaßen

Zeichnungsmaßen, often translated as "drawing dimensions" or "dimensional drawings," are a fundamental aspect of technical documentation. They are the numerical values and annotations placed on a technical drawing to specify the size, location, and orientation of geometric features of an object. The primary purpose of Zeichnungsmaßen is to provide unambiguous instructions for manufacturing, inspection, and assembly. Without them, a drawing would merely be a graphical representation lacking the precise information needed to create or verify a physical part.

The system of specifying dimensions is governed by standards, such as ISO or ASME, to ensure consistency and clarity across different industries and countries. These standards dictate not only the placement of dimensions but also the type of lines and symbols used. Common elements include dimension lines, extension lines, arrowheads, and the numerical value itself. Tolerances, which define the acceptable range of variation for a given dimension, are often included alongside the nominal dimension to control the precision of the manufactured part. Understanding and correctly applying Zeichnungsmaßen is crucial for engineers, designers, machinists, and quality control personnel to ensure that a manufactured product meets its intended specifications.
