When the circle is part of the border it is called the when it encloses a smaller center area it is called an (or tressure if other than circular shape). Linear circles are often placed in a design where a badge center or center emblem is to be placed for a fabricated medal. Once this is added to the base medal the linear circle forms a frame for the center emblem.

A raised line that is not a circle but outlines the area for later engraving, for instance, is called a CARTOUCHE. See also border.
