Grid Object
One grid establishes the pitch of the boat, another the pitch
of the ship.
A grid object is a type of helper object you can
create whenever you need a local reference g rid
or construction plane somewhere other than the
home grid.
You can have any number of grid objects in your
scene, but only one can be active at a time. When
active,agridobjectreplacesthehomegridinall

Youcanfreelymoveandrotategridobjects,
placing them at any angle in space, or attach them
to objects and surfaces. You can also change
viewports to display a plan or top view of any
active grid object.

Head Object
A head object is a component of a Target Camera,
Sunlight or Daylight system, or a Tape helper.
These objects comprise two components: the
target that the camera, sun, or tape points at, and
the head that represents the camera, sun, or tape.
The head object always points at the center of the
target.
Helper Object
3ds Max helper objects are used to help you set up
an animation, but do not render. Crowd animation
(page 2–1154) uses two kinds of specialized helper
objects: crowd (page 2–1187) and delegate.
Hide/Unhi de
You can hide any objects in your scene and you
have the option to hide any selection of objects or
to hide anything except your current selection of
objects. Hidden objects differ from frozen (page
3–945) objects in that they disappear from the
viewport instead of t urning dark g r ay. If you are
working on a scene that includes many objects
or you have many objects in a very tight area,
hiding some of them gives you more access to the
unhidden objects and speeds up redraws.
You can hide an object that includes a t arget
(such as target cameras, tape helpers, or suns) by
choosing either the head (page 3–951) or the target
object and then selecting hide.

Menus.
Hierarchical Link age
3ds Max uses a family-tree analogy to descr ibe the
relationship b etween objects lin ked together in a
hierarchy.
Paren t—An object that con trols one or more
children. A parent object is often controlled by
another superior parent object.
