title: A-frame: How to give a primitive like Ring or Cylinder depth?
body: <p>Is it possible to give a 2D primitive like Ring thickness/depth? I'm trying to make a 3D door with primitives and I want to make either a ring that has some depth or a cylinder with a thicker mesh. Even if it's at the three.js layer I would like to learn how to do this so I don't have to rely on imported 3D objects for the whole design.</p>
