This is fucking badass but as a semi-architect player that is way more vertically than I'd ever commit to. I usually map out what kind of floor plan my build will take and then scale the building to that size. I hope you've at least got a hoverpack!
I love stuff like that. When you get halfway through a build and realize you have to change plans and the way you end up getting it to work is something you'd never have come up with on its own, but it looks REALLY good.
Nice. I've been playing around with modular factories and transport recently, too. The hardest part seems to be committing after making a large enough factory to slowly squeeze past tier 6, but I've really taken to decorating the new facilities once they've been built.
Rotors and stators are next on my list. I made a large crystal oscillator factory this weekend that manages to pump out a whopping... 22/min.
