NAME
     CalcAxis - calculate lengths of principal axes

SYNOPSIS
     CalcAxis ( 0 | 1 ) ( 0 | 1 )

DESCRIPTION
     Generate a report with the relative lengths of the
     principal axes of all selected molecules. Only the
     selected atoms of each molecule are used, the same
     mass is used for all atoms.

     The lengths are listed relatively to the shortest axis,
     the average for all structures is given at the end.

     The first option selects whether a list with the angles
     of all selected bonds relative to the principal axes
     should be printed.

     The second option selects whether the principal axes
     should be displayed. A cylinder will be added, it can
     be manipulated with the corresponding commands, like
     LengthPrim and RadiusPrim. The created primitives have
     the properties "axis" and "cylinder".

     This command supports groups.
