Custom spacing

When is on, any not necessarily uniform sequence of offsets from the base plane can be defined.

The button can be used to sort the plane positions into ascending order.

We can also turn on thick cuts while using custom spacing.
See the comparison below when "Thick cuts" (with thickness is set to 60.0) is OFF and ON respectively:
