As we already saw, ZBrush 4.0 comes with a vast amount of brushes. But, if we take a closer look we'll see that there are, for example, 10 variations of the planar brush, so we can categorize them easily. Our three main brushes for hard surface sculpting, in this chapter, will be the Planar-, Polish, and the Trim brushes. Let's get an overview of what defines these brushes and how to use them.
The Planar brushes work like cutting off some part of the mesh, or making it planar, hence the name. This will give us plain surfaces with sharp edges, like goggles, for example.
The Trim Dynamic also creates planar surfaces, but changes its orientation while drawing across the surface. The Trim brushes allow for a more sketchy way of establishing hard surface areas.
The Polish brushes can create smooth surface transitions with low pressure and sharp creases with high pressure. This is somehow an all-rounder, used quite often.
With that said, let's see what we can make of this...
