A line that is drawn to show the edge and surface ridges of an object is typically referred to as an "outline" or "contour line." This line helps define the shape and form of the object, providing visual clarity and depth. In art and design, contour lines are essential for conveying three-dimensionality on a two-dimensional surface. They guide the viewer's eye and enhance the understanding of the object's structure.
