What is the purpose of continuous lines in design?

Continuous lines in design primarily serve to create a sense of transition. They guide the viewer's eye through a composition, leading them from one area to another in a smooth manner. This flow is essential in design as it helps unify various elements, enhancing the overall coherence of the piece.

For example, when used in a layout, continuous lines can connect various sections and create pathways that lead the viewer naturally through the content. This technique is crucial in both graphic and interior design, where the movement through the space or design is influenced by the lines that are present.

While continuous lines can also add visual interest, define boundaries, and highlight key elements, their main function is to ensure a seamless transition across the design, making the experience of the viewer more engaging and intuitive.
