@blanchsb Don’t underestimate the power of the human ‘subconscious’ (or unconscious as Jung would say, because sub sounds like ‘less than’…). Even if they won’t look at it they will still ‘feel’ the difference.
Do not model things that can’t be seen, like the ‘thread/winding’ of a bolt, but do model the hole where the bolt enters the material, if that makes any sense…
