The software-based lathe tool simulates a real lathe, which is a tool composed of a rotating base on which you place a cylinder of wood that is shaped by placing a steep blade on its surface as the base rotates around its vertical axis.

Cylinders and cones are commonly defined as polygonal objects and can be shaped by variables such as radius, height, number of longitudinal divisions, number of latitudinal divisions, and whether they are capped or not.
