Change here the position and orientation for a single group or a list of groups.
To modify a group, click over its graphic image, or write its identification
(name and number) on the 
Group entry. To modify a list of groups,
press the button 
List (after creating the list of groups with
Group->Select).  Parameters for empty entries or 
Local
choices remain unchanged.
To change a group name write the new name in the 
Group entry,
followed by the group number (GAMGI needs the number to identify the group).
To change the name for a list of groups, press 
List first
and then write the new common name in the 
Name entry.
Translation
The position of a group object can be changed using the 
X, 
Y,
Z entries. The change can be 
Absolute or 
Relative
(to the current position).
To go back to the initial position, set 
X, 
Y, 
Z,
to 
0, 
0, 
0, in 
Absolute mode.
Rotation
The orientation of a group object, defined by the Euler angles theta,
phi, psi, can be changed using the 
E1, 
E2, 
E3 entries.
The change can be 
Absolute or 
Relative (to the current
orientation). Euler angles are not addictive, so the group is
rotated back with the old angles and forward with the new ones.
To go back to the initial orientation, set 
E1, 
E2,
E3, to 
0, 
0, 
0, in 
Absolute mode.
