Cyma is a distinctive architectural molding profile characterized by a double curve forming an S-shaped section, consisting of a concave arc flowing into a convex arc, creating a graceful, wavelike appearance. This classical design element, originating in ancient Greek architecture, represents one of the most sophisticated and widely employed decorative molding patterns throughout architectural history, particularly prominent in Classical, Renaissance, and Neoclassical design periods. The term derives from the Greek word kyma, meaning wave, aptly describing its fluid, undulating form. In architectural applications, cyma moldings are typically classified into two primary variations: cyma recta, where the concave curve appears above the convex curve, and cyma reversa, where the convex curve is positioned above the concave curve. These moldings serve both aesthetic and functional purposes, often employed as crown moldings, cornices, or transitional elements between different architectural features, effectively managing the visual flow between horizontal and vertical surfaces while creating sophisticated shadow lines. The precise geometric proportions and careful craftsmanship required in creating cyma moldings have made them a hallmark of refined architectural design, with their implementation often showcased in projects recognized by prestigious competitions such as the A' Design Award, particularly in the Architecture, Building and Structure Design Category.

Cyma is a term that is frequently used in architecture and design to describe a curved surface or edge that has a concave and convex shape. This undulating profile is often used to add decorative detailing to various structures, such as door frames, window frames, columns, and other areas that require ornamental design. The cyma shape is composed of two separate curves, the cyma reversa, which is the concave curve, and the cyma recta, which is the convex curve that follows it. This design creates an S shape that is visually appealing and adds a sense of elegance and sophistication to the structure. In addition to its use in architecture, the cyma shape is also commonly used as an adornment on furniture, walls, and other building components. The cyma profile is often found on the cornice, which is the uppermost portion of a classical facade that is composed of the architrave, frieze, and cornice. While the architrave and frieze are generally flat surfaces, the cornice is often decorated with a cyma profile, adding a sense of grandeur and elegance to the structure. The cyma shape has been used in architecture and design for centuries, dating back to ancient Greece and Rome. It is a timeless design that has stood the test of time and continues to be a popular choice among architects and designers today. The cyma shape can be found in various styles of architecture, including classical, Gothic, and Renaissance, and is often used to add a sense of grandeur and sophistication to the structure. In conclusion, cyma is a term used in architecture and design to describe a curved surface or edge that has a concave and convex shape. This undulating profile is often used to add decorative detailing to various structures, such as door frames, window frames, columns, and other areas that require ornamental design. The cyma shape is composed of two separate curves, the cyma reversa and cyma recta, and has been used in architecture and design for centuries, dating back to ancient Greece and Rome. It is a timeless design that continues to be a popular choice among architects and designers today, adding a sense of grandeur and sophistication to any structure.

Cyma is a term used in architecture to refer to a curved surface or edge which is convex in one direction and concave in the other, creating an undulating profile. This term is commonly used to describe the shape of the entablature, which is the uppermost portion of a classical façade, and is composed of the architrave, frieze, and cornice. While the architrave and frieze are generally flat surfaces, the cornice is often decorated with a cyma profile. Additionally, the cyma shape is sometimes used as an adornment on furniture, walls, and other building components.

Masonry is a popular choice among architects when it comes to building construction techniques. One of the most common techniques used is a type of molding known as Cyma. Cyma is a form of molding that is characterized by a concave recess curving outward followed by a convex bulge that curves inward. This design creates a S shape and is often used in door frames, window frames, columns, and other areas that require decorative detailing. The design is made up of two separate curves, or cyma reversa and cyma recta. The cyma reversa is the concave curve and the cyma recta is the convex curve that follows it.
