Amazing MOC. I want to start some MOCs and was always in awe when I discovered something like this thing you built. Always wondered how do you proceed to achieve such complexity, I know the theory but in practice, you sit in front of your bricks and decide to do this thing, then what ? start building separate modules and fit them together ? do you model in LDD the gears and axles that make it tick and then tinker to add the structure to fit it in ? I would love some pointers on how to start ... sorry for the off topic
