are utilized as a transitional support piece in a cornice buildup, below the corona, under deep projections and above the frieze board. One reason they are used in a cornice buildup design is that the radius arc at the top of the profile is designed to lead one's eye to the next moulding element in the buildup, creating a smooth optical transition as well as carrying a load of weight. They can be used separately as a crown, but crown designs tend to have squared lines on the upper ends creating a termination point. The most common characteristics of these types of designs are the geometrical shapes of a radius arc at the top, vertical fillet positioned in the middle, and a cavetto/cove, cyma reversa or cyma recta located at the bottom of the pattern.
