What is one way center lines are typically represented in technical drawings?

Center lines are commonly represented in technical drawings using a pattern of long and short dashes that alternate. This specific line style is standardized in engineering and architectural drawings to clearly indicate the centers of circles, arcs, or symmetrical parts. The alternating long and short dashes provide a visual distinction that enables viewers to quickly identify the orientation and location of the center line, which is crucial for understanding the design intent and for accurate measurements. This line type is essential for any technical drawing as it helps convey critical information about the geometric properties of the objects being depicted.

Other representations that might be mentioned, such as solid lines or dashed lines, have different meanings in technical drawings and are used to convey different types of information. Solid lines typically represent visible edges, while dashed lines often indicate hidden edges or non-visible features. Therefore, the long and short dashes of center lines serve a unique and important role in the clarity of technical documentation.
