Region

The Region object is used to define a local coordinate system.  When a Region is specified for an object, its inputs for position and orientation are relative to the position and orientation of its Region.  The global coordinate system is the default for objects that do not reference a specific Region.

The Position and Orientation keywords are used to define the origin for the coordinate system and the angles for its coordinate axes.  Once these inputs have been set, it is advised to set the inputs for Show and Movable to FALSE so the Region object is no longer visible and cannot be moved accidentally.

The Scale keyword can be used to make the objects in a Region appear to be smaller and closer together compared to objects outside the Region.

Scale

The graphical scale for the Region's local coordinate system relative to the coordinate system in which it is embedded.  For example, an input of 0.5 would make objects appear to be one-half smaller and closer together.
