NL1, NL2
Lines to be concatenated. If NL1 = ALL, NL2 is ignored and all selected lines [LSEL] are concatenated. If NL1 = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). A component name may also be substituted for NL1 (NL2 is ignored).

将两条线连成一条线，划分网格时可能会用到，多于4条线时不能映射划分，可以用这个命令啊！

线的联合命令，划分网格时候可以把几根线连成一根线对待
