Circularity and roundness
WebOne theory suggests that our fascination with circular shapes can be traced back to our primitive ancestors. They used circles to fortify their dwellings, providing protection from predators and other dangers. This association with safety may explain why we still feel drawn to circular shapes.

WebCircularity definition, the state or quality of being in the shape or form of a circle: … WebMeasurements of roundness require 360 traces of the workpiece made with a turntable-type instrument or a stylus-type instrument. A least squares fit of points on the trace to a circle define the parameters of noncircularity of the workpiece. A diagram of the measurement method is shown below.
