What is a controlled line in art?

A controlled line in art refers to a line that is deliberately created with precision and intention, often used to convey a specific emotion or idea. Artists may use tools like rulers or compasses to achieve straight, uniform lines, or they may carefully control their hand movements to produce smooth, flowing curves. This technique can help establish structure, clarity, and focus within a composition, guiding the viewer's eye and enhancing the overall visual narrative. Controlled lines can be found in various art forms, including drawing, painting, and graphic design.
