Which lines assist in dimensioning by featuring short and long dashes alternately?

Center lines play a crucial role in dimensioning as they indicate the center of circular objects or symmetrical features. The alternating pattern of short and long dashes is a standardized method to visually represent these center lines clearly, allowing for accurate alignment and measurement in technical drawings.

This distinctive style helps differentiate center lines from other types of lines used in drafting. By making it visually distinct, they facilitate a quick understanding of the relationship between various components in a drawing, ensuring clarity in complex designs. Center lines are essential in any geometric or symmetrical layout as they help in accurately positioning and dimensioning related features. This use of short and long dashes is part of a unified drawing standard that aids engineers and architects in their communication and design processes.
