'lcmb' <name(char<9)>|'!' ['+|-' <line> '+|-' <line> '+|-' -> <line>..(up to 14 lines)]| ['ADD' '+|-' <line> '+|-' <line> -> '+|-' <line>..(up to 14 lines)]This keyword is used to define, extend or redefine a combined line (lcmb). Combined lines are necessary if the edge of a surface should be made of more than one line. Usually the user does not create lcmb's directly. They are created automatically during the process of defining a surface with the command qsur. There is no limitation to the number of lines in a combined line. However with one command, not more than 14 lines can be specified at a time. To specify more than that or to extend an existing lcmb a modify command has to follow. For example,
It should be noted that an existing lcmb can be converted into a spline with the command seqc.
