surf

       'surf' <name(char<9)|!> <line|lcmb> <line|lcmb> <line|lcmb> ->
       <line|lcmb>

This keyword is used to define or redefine a surface. It is a more convenient way to define a surface than the command gsur but it requires 3, 4 or 5 edges (lines or lcmbs) otherwise the surface will not be created. The most convenient way to define surfaces is to use the command qsur. If the name of the surface should be automatically generated, then just type ```!`'' instead of a name.
