By parenting the objects, you can move, rotate, or scale the cap and the
body as a single entity by selecting only the body.
Notice that the salt shaker displays horizontal curves that wrap around
the body. The curves are the original circles you used to loft the surface.
Because these curves are part of the surfaces construction history, you
can alter their shape if you decide you want to alter the shape of the body
and the body will update based on the construction history.
If you prefer not to see the curves in the scene view, select the curves and
select Hide Selection. The curves wont appear when you render an image
of the scene. Maya displays only surfaces, not curves, in rendered images.
Beyond the lesson
In this lesson you were introduced to the basic techniques related to lofting
curves to create NURBS surfaces:
You made a salt shaker with two surfaces: a body made from lofted curves
and a cap made from an altered sphere. An advantage of creating a separate
surface for the cap and base is that you can easily give each a different
color or texture, for example, one chrome and the other marble. Another
advantage of creating a separate cap is that you can animate the object
separately. For example, you could choose to animate the cap unscrewing
from the shakerBody.
You used a Loft operation rather than a Revolve operation to create the
body. The vertical corrugations on the surface would be impossible to
create by revolving a curve.
You can alter the position of the profile curves and the shape of the shaker
will update because of the construction history. If youre certain you wont
change the bodys shape by editing the shape of the lofted curves, you can
delete the bodys construction history to quicken Mayas processing of
your interaction with the surface. (For a surface as simple as the salt shaker,
deleting the history wont boost processing much.)
There are many other useful tools for creating and editing surfaces. For a
glimpse of the possibilities, take a look at the Surfaces menu and the Edit
NURBS menu.
