Ogee

[citation needed] The word was sometimes abbreviated as o-g as early as the 18th century,[1]: 218  and in millwork trades associated with building construction, ogee is still sometimes written similarly (e.g., as O.G.).

[citation needed] In architecture, the principal use of the term is to describe an arch composed of two ogees, mirrored left-to-right and meeting at an apex.

[6] A building's surface detailing, inside and outside, often includes decorative moulding, and these often contain ogee-shaped profiles—consisting (from low to high) of a concave arc flowing into a convex arc, with vertical ends; if the lower curve is convex and higher one concave, this is known as a Roman ogee, although frequently the terms are used interchangeably and for a variety of other shapes.

The aim of a mid-face rejuvenation is to restore the ogee curve and enhance the cheekbones, common parts of routine facelift surgery.

[citation needed] Due to the size and shape of such washers, they are generally manufactured as a cast iron product (in accordance with ASTM A47 or A48).

[citation needed] Weights supported by pulleys fell inside the ogee moulding and so were hidden from view.
