// Common useful shapes and structured objects.
// Some standard modules for making 3d shapes with attachment support, and function forms
// that produce a VNF. Also included are shortcuts cylinders in each orientation and extended versions of
// the standard modules that provide roundovers and chamfers. The sphereoid() module provides
// several different ways to make a sphere, and the text modules let you write text on a path
// so you can place it on a curved object.
