'surf' <name(char<9)>|'!' [<set>]|->
<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. Either individual lines or a set can be specified. To be meshable with structured elements it requires 3, 4 or 5 edges (lines or lcmbs). To be meshable with tr3u or tr6u it requires either to be plane or to reference a shape or nurbs which can not be provided with this command (see ``gsur. 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.
