SculptDraw This is the brush that appears by default in Sculpt mode.
SculptDraw creates hills or valleys (Figure 5.10) on a surface accord-

Brush selection button). The Draw and Brush brushes are very similar,
although Draw creates more powerful, yet less smooth, results.
Blob This brush alters whatever geometry is under the brush in a
spherical manner along the normals. When used subtractively, the
brush creates a void that appears in a similar shape as the inflation
(Figure 5.11.)
