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 five to seven surfaces to be mesh-able. However, the number of recommended surfaces is six. 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 a necessary placeholder for future functionality but has no actual meaning. Next, 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 an automatically generated name is desired, then type ”!” instead of a name.
