When creating groups of planes of a constant x, y, z location the name is zeroed on the first specified value and the remaining planes names are defined by the offset from the zero value. For example, 3 planes equally spaced by 0.1m starting from 1m or 3m would be named x-plane=0, x-plane=0.1, x-plane=0.2. How can planes be renamed efficiently when dealing with many of them?
