In
            addition to creating NURBS surfaces using curves, you can edit and
            sculpt surfaces and primitive objects in Maya using the Sculpt
               Geometry Tool.
         
         The Sculpt Geometry Tool allows
            you to interactively push or pull on the surface regions to create
            areas that are embossed or in relief in relation to the surface.
         
         In this lesson, you learn
            some of the basic concepts of these tools by sculpting a cartoon
            face and head from a NURBS primitive sphere using the Sculpt Geometry
               Tool.
         
         In this lesson you learn:
         
         
            - Basic sculpting operations (push, pull,
               smooth, relax and erase) with the Sculpt Geometry Tool.
            
- How the density of isoparametric lines
               affects the surface detail possible when sculpting.
            
- How to increase the surface subdivisions
               on a NURBS surface to aid with surface sculpting.
            
- How to change the brush radius for the Sculpt
                  Geometry Tool.
            
- How Opacity and Max
                  Displacement affect the sculpting operations.
            
- How to import geometry from a pre-existing
               file into your current scene.
