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.
