Minimize Number of Different Layouts
It is desirable to have a smaller number of different layouts computed by the nesting engine. That is, create layouts whose repeat count is high. This is like a secondary goal for the nesting engine. Flux Cut has the option to direct the nesting engine to minimize the number of different layouts, possibly resulting in a slight decrease in nesting efficiency.

For a sample job, below you can see how this setting affects nesting results.

When NC is released for the above example with the option selected, we will get four NC-codes instead of five.
