General

Sculpt Mode is similar to Edit Mode in that it is used to alter the shape of a model, but Sculpt Mode uses a very different workflow: instead of dealing with individual elements (vertices, edges, and faces), an area of the model is primarily changed using brushes.

Sculpting Mode Example.

Sculpt Mode is accessed from the mode menu of the 3D Viewport header or with the pie menu via Ctrl-Tab. Once inside Sculpt Mode, the Toolbar and Tool Settings of the 3D Viewport will change to Sculpt Mode specific panels. The cursor will change to a circle, to indicate the size of the brush.

To have predictable brush behavior, make sure to apply the scale of your mesh.

The following pages will briefly explain the fundamental features and concepts of Sculpt Mode, including various links to other pages for more details.
