■ Hard-Surface Sculpting 363Clip Brushes
Access the Clip brushes by pressing Ctrl+Shift. When selected, they will replace the default
selection Marquee or Lasso brushes. They function by creating a selection, which is flattened
into the rest of the model. Figure 10.39 shows a sphere before and after using ClipCurve.
Clip brushes have a feathered edge that represents the side that will be clipped.
You can move the Clip brush stoke by pressing the spacebar. If you discover you want to
clip the opposite side from the feathered edge, simply hold the Alt key and the clip plane will be
reversed. One useful trick is to press Ctrl+spacebar to open the menu shown in Figure 10.40.
Turning on Polygroup will cause ZBrush to automatically polygroup any faces you clip
(Figure 10.41).
