that tripod will change when you activate the
viewport it is in.
The coordinate system in Screen mode is always relative to the
point of view.
World—Uses the world coordinate system. Seen
from the front:
• X runs in a positive direction to the right.
• Z runs in a positive direction upward.
• Y runs in a positive direc tion away from you.
The World coordinate system is always fixed.
Par ent—Usesthecoordinatesystemoftheparent
of the selected object. If the object is not linked to
a specific object, it’s a child of the world, and the
parent coordinate system is the same as the world
coordinate system.
Example of a Parent object coordinate system
Local —Uses the coordinate system of the selected
object. An object’s local coordinate system is
carried by its pivot point (page 3–995).Youcan
adjust t he position and orientation of the local
coordinate system, relative to its object, using the
options on the Hierarchy command panel.
When Loca l is active, the Use Transform Center
button is inactive and all transforms use the local
axis as the center of t ransformation. In a selection
set of several objects, each uses its ow n center for
the transform.
Local uses an individual coordinate system for each object.
