Local Coordinate System
A book in object space rests on a table in world space. The book has its own local
coordinate system.
The local coordinate system is the coordinate system that relates specifically
to the selected object.
Each object has its own local center and coordinate system as defined by the
location and orientation of the object's pivot point. The local center and
coordinate system of an object combine to define its object space.
The direction of the object's X, Y, and Z axes depend on the current transforms
of the object. Contrast with the world coordinate system.
You can see the difference between the two coordinate systems when you
unintentionally rotate an object, such as a wheel on a car model , around the
world axis instead of the object's local axis. The wheel immediately flies off
in a large arc because the center of the rotation is at the origin of the world
coordinates.
