Hi Burr, yup I watched your video - but box modeling is not normally like that, it's more about punching out different polygons to make bumps and protrusions to add smaller details to a simple initial blocky shape.

The method you're showing is not like that at all, you're not adding in local details or stuff like that (local meaning just in one small area of the model and not doing something that spans the whole circular area of the revolve), you're making one large shape there...
