NGEN,[itim],[step],[n1],[n2],[inc],[dx],[dy],[dz]

generates a set of node lists by copying a node pattern, where:

• <itim> = total number of sets of nodes to be generated, not including the original pattern (default value: 1)
• <step> = increment to be applied to node numbers. If <step> is not specified, it will be set to <n2>-<n1>+1
• <n1>,<n2>,<inc>= pattern to be copied (default values for nodes: the last two nodes created; default value for <inc>: 1)
• <dx>,<dy>,<dz> = increments to be applied to the X,Y,Z node coordinates (default values: 0)
