👉 A fanback is a type of curve that can be formed by joining two or more straight lines in the form of a fan. It is often used in architecture, engineering, and design to create curves with a smooth transition between them. The fanback is typically defined as the distance between the ends of two straight lines that intersect at a right angle, and it is a crucial feature in many designs because it helps to achieve a more harmonious and aesthetically pleasing appearance.
