Cyma Recta
The other sheltering moulding, the Cyma Recta, is a curve of double flexure with upper fillet. Its proper employment is as the crowning member of the cornice, though, like the Cavetto, it is employed in other positions, notably as a plinth moulding, when it appears in a reversed position.
The projection is about equal to the height of the curved profile, the height of the crowning fillet being from one-fourth to one-fifth of the whole.
