gsur
'gsur' <name(char<9)>|'!' '+|-' 'BLEND|<nurbs>' '+|-' <line|lcmb> '+|-' ->
<line|lcmb> .. (3-5 times)
This keyword is used to define or redefine a surface in the most basic way (see also qsur). Each surface must have three to five lines or combined lines (see lcmb) to be mesh-able. However, the recommend amount of edges is four. For example,
gsur S004 + BLEND - L002 + L00E + L006 - L00C
will create the surface S004 with a mathematically positive orientation indicated by the ''+'' sign after the surface name. The keyword ''BLEND'' indicates that the interior of the surface will be defined according to Coons [12] or a NURBS surface is referenced. Use a ''+'' or ''-'' in front of the lines or lcmbs to indicate the orientation. These signs will be corrected automatically if necessary. If automatic name generation is desired, then use ''!
'' instead of a name.
