What does "revolve" accomplish in design work?

In design work, "revolve" is a technique used to create a three-dimensional shape by rotating a two-dimensional profile around an axis. This process is essential in software that deals with 3D modeling, allowing designers to form objects such as cylinders, spheres, or other complex shapes from simple 2D outlines.

When a profile is revolved, it essentially traces the outline of the shape as it spins around a fixed line (the axis), thereby generating a solid object. This method is particularly useful for designing parts like vases, bottles, or any symmetrical object, making it an important tool in both engineering and artistic design fields. By understanding this concept, students can better grasp how to use CAD software effectively and create intricate designs with precision.
