depends on the number of drawings you have. having worked on projects
(admittedly slightly larger than the neo...) with hundreds of
drawings, it helps no end having your fire protection set labelled
differently to the aircon, and again labelled differently to the
sanitary systems and structural steel.

i'd imagine the same could apply to the pcb layout, case mouldings,
and whatever other component sets you wish to separate
