More appropriate usage of memory.CONSTRUCT MERGE
The CONSTRUCT MERGE command is
extended to merge NURB CURVE lines. By default, curves will be merged (with other
curves) if 10 evenly spaced internal positions match within the tolerance. The number
of positions to check is controlled by the resource Femsys.*.Nurb.Merge.
You can also use the command line femgv -Merge value. For eample femgv -Merge 20
selects to check 20 positions, while -Merge -1 will prevent NURB Curves from being
merged (unless they have identical point+shape IDs).
