gbod

       'gbod' <name(char<9)|!> 'NORM' '+|-' <surf> '+|-' <surf> ->
       .. ( 5-7 surfaces )

This keyword is used to define or redefine a body in the most basic way (see also qbod). Each body must have fife to seven surfaces to be mesh-able. But six surfaces are recommended. The first two surfaces should be the ``top'' and the ``bottom'' surfaces. For example,
gbod B001 NORM - S001 + S002 - S005 - S004 - S003 - S006
will create a body B001. The keyword ``NORM'' is necessary but has no meaning up to now. Then follow the surfaces with a sign ``+'' or ``-'' in front that indicates the orientation of each surface. These signs will be corrected automatically if necessary. If the name of the body should be automatically generated, then just type ```!`'' instead of a name.
