Change here the position and orientation for a single plane or a list of planes.

To modify a plane, click over its graphic image, or write its identification (name and number) on the Plane entry. To modify a list of planes, press the button List (after creating the list of planes with Plane->Select). Parameters for empty entries or Local choices remain unchanged.

To change a plane name write the new name in the Plane entry, followed by the plane number (GAMGI needs the number to identify the plane). To change the name for a list of planes, press List first and then write the new common name in the Name entry.

### Translation

The position of a plane 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 plane 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 plane 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.
