Line styles refer to the different ways lines can be drawn in graphic design, drafting, and computer graphics. Common styles include solid lines, dashed lines, dotted lines, and dash-dot lines. Each style serves a specific purpose, such as indicating boundaries, paths, or different types of relationships in diagrams. In technical drawings, line styles help convey information clearly. For example, a solid line often represents visible edges, while a dashed line may indicate hidden features. Understanding these styles is essential for interpreting blueprints, maps, and other visual representations in fields like architecture and engineering, where clarity is crucial.
