+Alignment for digital controls
+------------------------------

+For backwards compatibility reasons, ``Justification ( 1 )``, ``Justification ( 2 )`` and 
+``Justification ( 3 )`` all lead to a left alignment of the digital in 3Dcabs.

+``Justification ( 5 )`` must be used for center alignment, and ``Justification ( 6 )`` 
+must be used for right alignment. ``Justification ( 4 )`` leads to left alignment.
