Revolution

Definition

In the context of mechanical engineering design, a revolution refers to a complete turn or rotation of a body around a central axis. This concept is crucial in both 2D drafting and 3D modeling, as it helps in creating shapes and features that are symmetrical and rotationally symmetric, such as gears, wheels, and other circular components.
